A kangaroo can jump over an object 2.56 m high.
(a) Calculate its vertical speed (in m/s) when it leaves the ground.
A ball rolls off a 1.8 m high table with an initial speed 3.5. When it hits the ground, how far away (horizontally) has it traveled? Answer in meters.
If an object were to freely, from what height would it need to drop to reach a speed of 70.0m / s before reaching the ground?
