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

when v = 0, we are at the top
v = Vi - g t
0 = 500 - 9.81 t
solve for t

multiply t by 2 to get total time (parabola up to vertex and back down, symmetry)
