A wagon with its passenger sits at the top of a hill. The wagon is given a slight push and rolls 200 m down a 16° incline to the bottom of the hill. What is the wagon's speed (in m/s) when it reaches the end of the incline? Assume that the retarding force of friction is negligible.
_? m/s

5. A 1000-kg car is at the top of a hill as shown, where its elevation above the bottom of the hill is 120 m. a. What is its gravitational potential energy? 120 m b. If the cart starts from rest and rolls down the hill with negligible friction and air resistance, what will its kinetic energy be when it reaches the bottom? c. What will be its speed when it reaches the bottom? Suppose instead that there is noticeable...
2. A 40.0 kg wagon is towed up a hill inclined at 17.5° with respect to the horizontal, The tow rope is parallel to the incline and has a tension of 542 N. Assume that the wagon starts from rest at the bottom of the hill, and neglect friction. (a) How fast is the wagon going after moving 73 m up the hill? (b) What is the magnitude of the normal force acting on the wagon? 3. A 5.00 kg...
Vo 5) h 200 m A driver coasts down a hill 200 m high with initial speed vo 40 m/s. The road has friction that results in a negative work -1.7 x 10 J. The effect of this is that the total initial energy is reduced by this amount by the time the car reaches the bottom of the hill. Calculate the speed of the car when it reaches the bottom of the hill. The mass of driver and passenger...

A ball rolls down a 72 meter hill. The initial velocity at the top of the hill is 0 m/s. The ball reaches the bottom of the hill after 12 seconds. Is there a point in time where the ball travels at a speed of 5 m/s or greater? explain
Starting from rest, a basketball rolls from the top to the bottom of a hill, reaching a translational speed of 6.2 m/s. Ignore frictional losses. (a) What is the height of the hill? (b) Released from rest at the same height, a can of frozen juice rolls to the bottom of the same hill. What is the translational speed of the frozen juice can when it reaches the bottom?

3. A roller coaster sits at the top of a hill and is preparing to enter a loop-the-loop as shown below. The hill has a height of 86.0 meters, the loop has a radius of 22.0 meters and the roller coaster has a mass of 525 kg. Assume h=0 at the bottom of the hill. a) What will be the velocity of the roller coaster when it reaches point C? A b) What will be the velocity of the roller...
