Question

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

Answer 1

Explanation:

u = 20m/s

v = 0 m/s

g = 10 m/s

if a ball is thrown upward its final velocity be 0 and it gets acceleration due to gravity,

now,

v = u + gt

t = v-u/g

= 20/10

= 2 s
