If a person were walking at the average speed of 2.5 mph from District 12 to District 13 and it takes a week to get there, how fast is the hovercraft traveling from District 12 to District 13, which makes it there in 45 min?

1) the arrow sticks into the solid after hitting it?
2) the arrow bounces off of the cube perfectly elastically?

You have a very long ramp with an inclination of 35 degrees. You give a hollow sphere a translational velocity of 23 m/s toward the base of the ramp. The sphere has a mass of 4 kg and a radius of 0.25 m.
a) What is the hollow sphere's total kinetic energy before rolling up the ramp?
b) To what height above the ground will the sphere roll up the ramp before rolling back down? Assume that it rolls without slipping.
