Question

An object is thrown straight upward from the edge of a building with a velocity of 20m/s. Where will the object be 5s after it was thrown

Answer 1

Explanation:

V = S/t

s =vt

d = 20 x 5

d = 100m

Answer 2

Answer:

100m/s

Explanation: 5seconds at 20ms/s puts it 100ms. But due to  gravity it will slow down. The equation for the effect of gravity is too complex for me. But assuming that gravity does not exist then it would be 100ms.
