You're standing at the top of a snow-covered hill, sloped at 20.0°. The coefficient of kinetic friction between your sled and the hill is 0.534. Unfortunately, there's a running stream just at the bottom of the hill, and you don't want to get wet. If you and your sled together have a mass of 87.0 kg, with what speed should you push off with to stop just before the stream, 77.0 m down the slope?

A makeshift sign hangs by a wire that is extended over an ideal pulley and is wrapped around a large potted plant on the roof as shown in Figure P6.10. When first set up by the shopkeeper on a sunny and dry day, the sign and the pot are in equilibrium. Is it possible that the sign falls to the ground during a rainstorm while still remaining connected to the pot? What would have to be true for that to be possible? FIGURE P6.10 Problems 10 and 11.
Sally wants to hang up some decorations on the side of her house, so she props up a ladder of length L = 3m against a wall at an angle of θ = 50° with respect to the horizontal. The ground is somewhat icy, where the coefficient of static friction between the ground and the ladder’s feet is µ = 0.55; while the wall of her house can be considered frictionless. If Sally has a mass of 60kg and the ladder has a mass of 80kg, what is the max distance that she can climb up the length of the ladder without it slipping? You may assume the ground is perfectly flat, and the wall is perpendicular to the ground.
A 80.0 kg skater with the Birmingham Bulls hockey team with an initial speed of 7.8 m/s stops propelling himself and begins to coast across the ice, eventually coming to rest. The coefficient of kinetic friction between the ice and the skate blades is 0.100, and air resistance can be neglected. How far will the skater travel before coming to rest?
You are the physics consultant working on an action movie set where an SUV must start from rest, accelerate along a pier, and jump over a stretch of water to land in a departing ferry. (The director assures you it will all be very exciting.) The drawing below shows the situation. The SUV has four-wheel drive (see problem N5D.1), and the coefficients of friction between the tires and the pier’s surface are us =3/4 and uk = 1/2. Calculate the length L (as a fraction or multiple of D) of the run along the pier that you will need for the SUV to make it to the ferry. Ignore air drag.
Blocks A, B, and C are placed as shown in the figure and connected by ropes of negligible mass through the pulleys of neglible mass and friction. Both blocks A and B have mass mA=mB= 2.5 kg each while the mass of block C is mC= 6.5kg . The coefficient of kinetic friction between blocks A and B and the surface is μk= 0.4. Initially, the system is at rest. Once released, the blocks move rightward, Find the magnitude of the acceleration of the system. Find the magnitude of the tension in the cord connecting blocks A and B. How far does block A move in the first 0.5 s (assuming it does not reach the pulley)?
A 1500 N block is in contact with a level plane whose coefficient of kinetic friction is 0.12. If the block is acted upon by a horizontal force of 250 N, what time, in seconds, will elapse before the block reaches a velocity of 14.5 m/s, starting from rest?
A 200-g hockey puck is launched up a ramp that is inclined at a 30° angle above the horizontal. The coefficients of static and kinetic friction between the puck and the ramp are µs = 0.40 and µk = 0.30, respectively, and the puck's initial velocity at the base is 3.8 m/s parallel to the sloping surface of the ramp. What speed does the puck have when it slides back down to its starting point?
David throws a 50 kg cart down a ramp with an initial speed of vi = 6 m/s. The ramp is at an angle of 20◦, and the coefficient of kinetic friction between the cart and the ramp is µk = 0.25. Additionally, the coefficient of static friction is µs = 0.55. How much time does it take to reach Ryan who is 10 m away? Assume that the cart slides and doesn’t roll.
The crate, which has a mass of 100 kg, is subjected to the action of the forces. If it is originally at rest, determine the distance it slides in order to attain a speed of 6/m. The coefficient of kinetic friction between the crate and the surface is µk=0.2.
The engines of a tanker broke down and the wind pushes the ship with a constant speed of 1.5 m / s straight towards a reef. When the boat is 500 m from the reef, the wind stops and the engineer manages to start the engines. The rudder is stuck, so the only option is to try to accelerate backwards. The mass of the ship and its cargo is 3.6 x 107 kg and the engines produce a net horizontal force of 8 x 104 N. The hull can withstand impacts at a speed of 0.2 m / s or less. The retarding force that the water exerts on the hull of the ship can be neglected. a) The equation of motion that corresponds to the horizontal component is? b)The acceleration of the ship is equal to? c) If the reef does not exist, the vessel, before stopping, travels what distance?
Read the scenario. A cyclist is riding his bike at a constant speed of 5 m/s, and experiences a frictional force between the bike and sidewalk of 100 N. The cyclist then changes his speed to 10 m/s. What effect does this increase in speed have on the frictional force between the bike and sidewalk? A) The frictional force doubles because when speed increases frictional force also increases. The frictional force doubles because when speed increases frictional force also increases. B) The frictional force becomes half of what it was because when speed increases, frictional force decreases. The frictional force becomes half of what it was because when speed increases, frictional force decreases. C) The frictional force between the bike and sidewalk stays the same because speed does not affect frictional force. The frictional force between the bike and sidewalk stays the same because speed does not affect frictional force. D) The frictional force increases, but does not…
In February 1955, a paratrooper fell 370 m from an airplane without being able to open his chute but happened to land in snow, suffering only minor injuries. Assume that his speed at impact was 56 m/s (terminal speed), that his mass (including gear) was 85 kg, and that the magnitude of the force on him from the snow was at the survivable limit of 1.2 *105 N.What are (a) the minimum depth of snow that would have stopped him safely and (b) the magnitude of the impulse on him from the snow?
