HELP on Physics HW:?

Question

I need help on this problem:

Find the horizontal range of a baseball that leaves the bat at an angle of 63 degrees with the horizontal with an initial velocity of 160 km/h. Disregard air resisitance.

Answer 1

conversion 160km/h = 44.4 m/s

Horizontal component = 44.4 * cos 63 = 20.2 m/s
Vertical component = 44.4 * sin 63 = 36.6 m/s

Total time in air = 2 * (36.6 - 0) / 9.81 = 7.46 s

Range = 20.2 * 7.46 = 151m
