Motion Under Gravity question?
A ball is thrown vertically upwards from ground level with initial speed of 7m/s. Assume that no resistance forces act on the ball, so it moves only under the influence of gravity.
a) Find the maximum height of the ball
Answer: 2.5m
b) The ball hits the ground T seconds after it was thrown. Find T
-----
useful equations:
s=ut+1/2at^2
v=u+at
v^2=u^2+2as
Where: S = displacement U = initial velocity T = change in time A = acceleration V = final velocity
For b), can you please explain how you got your answer as coherently as possible. I have the answer at the back of my textbook, I just don't know how to get to it.
Thanks!
