Question

16. A ball is gently dropped from a height of 15 m. If its velocity increases uniformly at the rate of 10 ms 2, with what
velocity will it strike the ground ? After what time will it strike the ground ?​

Answer 1

for freely falling body,the final velocity is

$\sqrt{2gh}$

=

$\sqrt{2.10.15}$

=

$\sqrt{300}$

=10√3 m/sec.
