Determine whether a baseball hit 4ft above ground at 115ft per second at an angle of 25 degrees relative to level ground will clear a 10-foot wall 310 ft away.

Question

I need help with the steps and answer 

Answer 1

Assuming the ball is traveling at a uniform velocity at 115 ft per second at an angle of 25 degree after getting hit.

The horizontal velocity component = 115 cos 25 = 104 ft/s

Time to cover 310 ft = 210/104 = 2 s

The vertical initial velocity component = 115 sin 25 = 48.6 ft/s

Distance the ball travels above 4 ft = 48.6*2 + 0.5(-32)*2² = 33.2  (using s = ut - 2gt²)

Clearly, the ball will clear the 10-ft wall.
