The 20kg object is dropped from a height of 2 meters. Find its speed when it hits the ground. Give your answer in meters per second.

There's an easy formula to figure out how fast something will be at the end of a fall.
Square root of (2gh).
Mass isn't even involved
Sq.Rt.(2 x 9.8 x 2)
Sq.Rt.(39.2)
6.26 m/s 
Speed =d×t. =55×10=550
