a)
Acceleration of stone = 10

Integrate:
So velocity = 10t

Integrate again:
So distance from starting point = 5t^2

Distance from ground = 450-5t^2

b)
450 - 5t^2 = 0


9.48 seconds

c) velocity = 10t

Put the time into this to give:

94.8 m/s

d.

Velocity = 10t + 5

Integrate again:

5t^2 + 5t


Solve
5t^2 + 5t = 450

Gives 9 seconds
