In a 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° with respect to the flat roof while traveling at aspeed of 5.0 m/s. Will he make it to the other roof, which is 2.5 m shorterthan the building he jumps from?

I need helping finding the equation for time to then get the equation for delta y, any help?

anonymous · Answer

x =xi + vt + 1/2at^2 for x direction to find time

anonymous · Answer

plug into same equation for y direction

anonymous · Answer

The only problem is that I don't have the initial velocity to find it

anonymous · Answer

5.0 m/s, but it's at an angle. use trig!
