Question

A stone thrown vertically upwards with an initial velocity 50m/sec comes to a stop in 5 sec. Find the retardation

Answer 1

Answer:

A pebble thrown vertically upwards with an initial velocity 50 ms

−1

comes to a stop in 5 s. Find the retardation assuming displacement in upwards direction to be positive.

Answer 2

Answer:

u=50m/s

v=,0m/s

t=5sec

so, acceleration=v-u/t

=0-50/5

=-10m/s^2
