Grug is a creature formed from the top of a Burrawang tree, standing ~1.25m tall. One day, Grug climbs a playground slide of 2.6 m height, and slides down its largely frictionless surface. The bottom of the slide is 69 cm above the ground. With what speed does Grug leave the slide? (Units: m/s)
A spring gun has a spring constant of 50 N/m and is compressed by 5 cm. It is used to launch a ball of mass 100 g. What is the speed of the ball when it leaves the gun? The same spring gun is used to shoot the ball vertically upward. What is the maximum height reached by the ball?
The drawing shows two boxes resting on frictionless ramps. One box is relatively light and sits on a steep ramp. The other box is heavier and rests on a ramp that is less steep.

A sledgehammer of mass m = 1.1 kg falls freely vertically downward from a height of h = 2.5 m at an initial speed of v = 11.5 m/s before striking a partially buried piling. After the blow the piling has moved d = 0.065 m deeper. How much kinetic energy, in joules, does the sledgehammer have just before striking the piling? How much force, in newtons, was applied to the piling? Assume all the energy goes towards driving the piling into the ground, and the force of the sledgehammer is constant over the distance d that the piling is driven into the ground. Note that you can ignore the change in potential energy of the piling itself. Further, because d is so small compared to h, you can also ignore the change in potential energy of the hammer as well as it moves distance d.
The desperate contestants on a TV survival show are very hungry. The only food they can see is some fruit hanging on a branch high in a tree. Fortunately, they have a spring they can use to launch a rock. The spring constant is 1300 N/m, and they can compress the spring a maximum of 38 cm. All the rocks on the island seem to have a mass of 480 g. With what speed does the rock leave the spring?
A ball of mass m= 0.38 kg is tied to a massless string of length L=1.2m. The ball is released at rest from point A as shown in the figure. a) What is the speed of the ball as it passes through point B? b) What is the tension in the string at point B?
Sara throws a baseball to Janice. The baseball has a mass of 0.142kg. It is 1.1m above the ground, moving at 15m/s when sara lets go of it. Ignore the effects of air resistance. The baseball is moving horizontally at 13m/s when it reaches maximum height. Calculate the maximum height reached by the baseball.
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.
