Question

A ball is thrown upward at 6m/s. time for the ball to return to thrower? time to reach max height?

Answer 1

Do you have any intention of even attempting your homework, or were you planning on cheating on the exam as well?

Answer 2

the ball will reach maximum height when its vertical velocity is zero

this occurs when:

V(t)=V0-gt

or when V(t)=6m/s-9.8m/s/s t

t=6/9.8 s

the time to return to thrower is just double this time
