Question

A juggle maintains four balls in motion, making each of the them to rise a height of 20m from
his hand The time interval that he should maintain, for the proper distance between them is
(take g=10m/s2
)

Answer 1

Answer:

Explanation:s=ut+1/2gt²

u=0

g=10m/s²

s=20m

Now,

20=0*t+1/2*10*t²

20=5t²

t²=20/5

t²=4

t=√4

t=2 sec

Therefore, time interval that he should maintain should be of 2 seconds for the proper distance between them.
