On Earth, you are able to consistently hit a golf ball 156 meters when you use your Five-iron which launches the ball at a 23 degree angle with respect to the ground. If you were able to perform this same shot with the same club on the surface of the moon, where acceleration due to gravity is 1.62 m/s^2, how far are you able to hit the ball?
Compare the gravitational lens to the one found in a telescope.
A ball (m=1kg) is dropped from a height of 3 m. Assume no air resistance. After it bounces off the ground it only reaches a height of 2 m. What is the balls change in energy
The height of a helicopter above the ground is given by h = 2.95t^3, where h is in meters and t is in seconds. At t = 2.50 s, the helicopter releases a small mailbag.
A rope can withstand 1.0 x 10^3 N of tension. If the rope is being used to pull a 10.0-kg package across a c=frictionless surface, what is the greatest acceleration that will not break the rope
