A 10 kg ball is released from the top of a hill. How fast is the ball going when it reaches the base of the hill? Approximate g as 10 m/s2 and round the answer to the nearest tenth.

m/s

You need the height h of the hill to get a numeric speed. By energy conservation (mgh = ½mv^2) the mass cancels and

v = sqrt(2gh).

With g = 10 m/s^2 this becomes

v = sqrt(20h) m/s.

Give the height h (in meters) and I’ll compute the speed rounded to the nearest tenth. (For example, if h = 10 m, v = sqrt(200) ≈ 14.1 m/s.)
