Please ans me fast​

Answer 1

Answer:

ball thrown up so total time in going up and comming down is 6 sec so time to only come down is 6÷2=3

now it returns to hand that means final velocity is 0

u that is initial velocity is to be find so apply 1st equation of motion

v=u+at here a is equal to minus of g

0=u-gt

u=gt

u=10×3

u=30 metre per sec

hope it helps,!
