A 3kg cat falls out of a window that is 10m above the ground and lands safely in the grass. Calculate the velocity at which the cat hit the ground.

What do you think car designers do if the damage caused by a crash test is too severe?

If a 2 ounce coin is dropped from the top of the washington monument and has a final velocity of 300 mph (miles per hour) when it hits the ground, how much kinetic energy will it have at that time?

If a car is traveling on the highway at a constant velocity, the force that pushes the car forward must be a. equal to the weight of the car. b. less than the force of friction exerted upon the car. c. equal to the force of friction exerted upon the car. d. greater than the weight of the car.
