A 1 kg ball is fired from a cannon directly upwards in an airless chamber. Its initial speed is 10 m/s, and it reaches a height of 5 m before falling due to Earth's gravity. If a 2 kg ball is fired at 20 m/s directly upwards, what height will it reach before it begins falling, rounded to the nearest meter? Acceleration due to gravity is 10 m/s^2

A cannon fires a 0.292 kg shell with initial velocity vi = 8.2 m/s in the direction θ = 45 ◦ above the horizontal. The shell’s trajectory curves downward because of gravity, so at the time t = 0.643 s the shell is below the straight line by some vertical distance ∆h. Find this distance ∆h in the absence of air resistance. The acceleration of gravity is 9.8 m/s 2 . Answer in units of m.

On Mars, a ball is rolling from a ground to a hill, and we know the height of the hill, Z, is 10 m, and the initial velocity ofthe ball on the ground and the final velocity on the hill are known: V1 = 20 m/s and V2 = 10 m/s, respectively. The mass ofthe ball, m, is 4 kg. The gravitational acceleration on Mars, gMars, is 3.7 m/s2. Please calculate 1) the change in kineticenergy, ΔKE, in J and 2) the change in potential energy, ΔPE, in J, of the ball for the rolling process.
A skater with mass 65 kg is skating on a horizontal surface at a constant speed. There is a ramp ahead, and the skater has just enough speed to make it to the top of the ramp (meaning the speed at the top of the ramp is 0 m/s). The height of the ramp is 1.9 m. Answer the following 5 questions. In this problem, set the reference point of the height at the horizontal surface, and use g = 9.8 m/s2 for the acceleration due to gravity. Ignore air resistance and friction unless otherwise stated. At the top of the ramp, Person A pushes the skater down the ramp. When the skater goes down to the horizontal surface, he is moving at the speed of 9.2 m/s. What is the work done by Person A on the skater during the push? There is another ramp of the height 2.5 m. What is the speed of the skater at the top of this ramp?
