A golfer hits a golf ball at an angle of 35° above horizontal. If the initial velocity is 55 m/s, how long does the ball soar before it hits the ground?

• Physics -

initial speed up = 55 sin 35 = Vi
v = Vi - 9.8 t
v = 0 at top
so
0 = 55sin 35 - 9.8 t
solve for t

First statement is correct, bottom two answers are wrong. Remember to multiply time by 2 to give the time up and time down again.
