A bullet fired from a gun vertically upward with a muzzle velocity of 500 m/s. A) How long is the highest point reached? B) How long does it take the bullet to reach the ground after it is fired?

Answer 1

A. V = Vo + g*t = 0
500 - 9.8t = 0
9.8t = 500
Tr = 51.02 s. = Rise time = Time to reach max ht.

B. T = Tr+Tf
Tf = Tr = 51.02 s. = Fall time.
T = 51.02 + 51.02 = 102.04 s. to reach
