A skier starts at rest at the top of a large hemispherical hill (Fig. P7.63). Neglecting friction, show that the skier will leave the hill and become airborne at a distance h = R/3 below the top of the hill. Hint: At this point, the normal force goes to zero. Figure P7.63
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.
6. A loaded 425 kg toboggan is traveling on smooth horizontal snow at 5.40 m/s when it suddenly comes to a rough region. The region is 8.00 m long and reduces the toboggan's speed by 1.50 m/s. (a) What average friction force did the region exert on the toboggan? (b) What is the coefficient of kinetic friction between the toboggan and surface ?
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?
A child shoves a 4.6 kg block so that it starts traveling across a level floor with an initial velocity of 3.6 m/s. If the coefficient of kinetic friction between the block and the floor is 0.29, how far will it travel before coming to rest? d = m
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?

A constant applied force ?p of 15.0 N pushes a box with a mass ?=6.00 kg a distance ?=15.0 m across a level floor. The coefficient of kinetic friction between the box and the floor is 0.150.Assuming that the box starts from rest, what is the final velocity ?f of the box at the 15.0 m point If there were no friction between the box and the floor, what applied force ?new would give the box the same final velocity?
A 10 kg block with an initial velocity of 10 m/s slides 10 meters across a horizontal surface and comes to rest after sliding for 2 seconds. How much force was acting on the block to make it stop? Your answer should be in units of N but you should only submit the number for your answer (and don't worry about negative signs, just submit a positive value).

What speed does the puck have when it slides back down to its starting point?
