A ball is thrown vertically upwards at 3 m s-1 from 1m above ground level (I) write down the equation for the height of the ball above the ground after t seconds (while the ball is in the air). (II) use your answer to find the time it takes the ball to reach the ground. (iii) how fast is the ball moving just before it hits the ground (IV)State an assumption you have made

I believe the first answer could be h= 3t+1, not sure how to begin
Answered by Steve
h = 1 + 3t - 4.9t^2

You forgot about gravity
