In the scene in an action movie, a stuntman jumps from the top of one building to the top of another building 4.0 m away. After a running start, he leaps at an angle of 15 degrees with respect to the flat roof while traveling at a speed of 5.0 m/s. Will he make it to the other roof, which is 2.5 m shorter than the building he jumps from. I've been stuck on it for so long...I can't find out what (a) in the equation would be. Please help.

anonymous · Answer

Y :  0 =2.5 + 5sin15*t - (1/2)*g*t^2
solve for t; use in:

X:  x= 5cos15*t
if x>= 4, he makes it.
