A rollercoaster cart of mass 400kg is moving at the top of the first hill (25m high) at a speed of 3.3m/s. It comes down to the ground at the bottom of the hill, then goes back up a second, smaller hill of height 9m. Assuming no air resistance or friction, what is the speed of the cart at the top of the second hill? 18m/s 13.2m/s 22.4m/s 31m/s OO O

A spring-loaded toy gun is used to launch a 10 g plastic ball. The spring, which has a spring constant of 10N/m is compressed by 10 cm as the ball is pushed into the barrel. When the trigger is pulled, the spring is released and shoots the ball back out horizontally. a) What is the ball's speed as it leaves the barrel? Assume the friction is negligible. b) If the toy gun was shot vertically upward, how high would the ball go? Use energy concepts.
A 108 kg man is skiing across level ground at a speed of 9.5 m/s when he comes to the small slope 1.2 m higher than ground level shown in the following figure. -8.0 m- f1.2 m (a) If the skier coasts up the hill, what is his speed (in m/s) when he reaches the top plateau? Assume friction between the snow and skis is negligible. 8.16 m/s (b) What is his speed (in m/s) when he reaches the upper level if a 75 N frictional force acts on the skis? 6.31 X m/s

QUESTION 8 OK, same sort of track, but now with d = 2.10 m. Now suppose the blocks starts on the track at x = 4.76 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case? A 8.30 m/s B 14.55 m/s C 10.29 m/s D 17.39 m/s
On board the starship Serenity, Captain Mal has two boxes connected together by a cord that passes over a massless, frictionless pulley mounted on the ceiling of the storage bay. The first box has a mass of 252.0kg and the second box has a mass of 278.0kg. If the 278.0kg box starts off at rest 2.60m above the ground, find the speed of the box when it reaches the ground. Assume the gravity on Serenity is 9.80m/s2.

A 51.2 kg sled coasts down a hill, starting from rest. The hill is inclined at an angle of 20.8 degrees with respect to the horizontal and has a height of 7.25 m. The sled's blades have recently been greased so that the sled slides down the hill without friction. What is the final speed of the sled (in m/s) just as it reaches the bottom of the hill? Use g = 9.81 m/s2.

* Incorrect. A proton (mass m = 1.67 × 10-27 kg) is being accelerated along a straight line at 2.00 × 10¹1 m/s² in a machine. If the proton has an initial speed of 1.30 x 105 m/s and travels 5.60 cm, what then is (a) its speed and (b) the increase in its kinetic energy? (a) Number i 3.28E-22 (b) Number i Units Units J
