A 9.50 kg block is at rest on a horizontal floor, and then you pull it with a cord that exerts a tension force of 12.0 N on the block at an angle of 24.0o above the horizontal. The coefficient of kinetic friction between the block and the floor is 0.055. What is the speed of the block 0.85 s after it starts moving? Nothing I do is working! I only have three more tries to get it right and what should be working is not.

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.
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.
A 2.00 kg box is moving to the right with speed 9.00 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t) = (6.00 N/s2)t2. (a) What distance does the box move from its position at t = 0 before its speed is reduced to zero? (b) If the force continues to be applied, what is the speed of the box at t = 3.00 s?
A 3.00 kg box is moving to the right with speed 8.00 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t)=( 6.00 N/s2 )t2 What distance does the box move from its position at t=0 before its speed is reduced to zero? If the force continues to be applied, what is the velocity of the box at 3.00 s ?
A 5 kg block is at rest on a horizontal floor, and then you pull it with a cord that exerts a tension force of 14 N on the block at an angle of 22 degrees above the horizontal.

A freight train consists of two 8.00×104 kg engines and 45 cars with average masses of 5.60×104 kg. (a) What force ( in N) must each engine exert backward on the track to accelerate the train at a rate of 4.00×10−2 m/s2 if the force of friction is 6.20×105 N, assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains is small, and consequently trains are very energy-efficient transportation systems. answer= N (b) What is the force ( in N) in the coupling between the 37th and 38th cars (this is the force each exerts on the other), assuming all cars have the same mass and that friction is evenly distributed among all of the cars and engines? answer = N
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?
John is building a frictionless track with a block (? = 20.0kg) sliding on it (no flying up). The block is initially at rest at point A, and it is pulled by an external force ? = 60.0N (with an angle ? = 25.0 ° from the surface of the track) over a distance ? = 3.50 to point B. There are no external forces on the block after point B and the block continues to slide along the track until the magnitude of its velocity is ?C = 0.700m/s at point C. What is the height ℎ of point C (relative to point A)?
A movie stunt performer is filming a scene where he swings across a river on a vine. The safety crew must use a vine with enough strength so that it doesn't break while swinging. The stunt performer's mass is 88.0 kg, the vine is 12.0 m long, and the speed of the stunt performer at the bottom of the swing has been determined to be 7.80 m/s. What is the minimum tension force (in N) the vine must be able to support without breaking? ____N
