Question

A body is thrown upwards with a velocity of 20 m/s. How much time will it take to return to its original position?
Step by step Answer​

Answer 1

Explanation:

Given that,

Initial velocity u=20m/s

Final velocity v=0

Now, from equation of motion

v=u−gt

0=20−10t

t

1

=

10

20

t

1

=2s

Total time

t=2t

1

t=2×2

t=4s

Hence, the time is 4 s
