Question

Q11. A ball is dropped from a height of 40 m. If the velocity increases uniformly at the rate of
20m/s^2, what will be the velocity when it strikes the ground. After what time will it strike the
ground?​

Answer 1

Answer:

u=0

v=40

acc. =20m/s square

t=?

20=40-0/t

20t=40

t=40/20

=2s
