A stone is thrown vertically upwards with spred 15ms-1 from a point 5 m above ground level. Modelling the stone as a particle find:
a) its height above ground level after 2 seconds
b)the time taken for the stone to reach its maximum height
c)the time taken for the stone to return to the point from which it was thrown
d)the speed of the stone when it is 12m above ground level
for a I got 20m but do not know what to do for b, c, d.
Thanks in advance.
