In a scene in an action movie, a stuntman jumps from the top of one building to the top of another building 4.0m away. After a running start, he leaps at an angle of 15 degrees with respect to the flat foor 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? help please, thanks:)!

Calculate how far he travels horizontally before falling 2.5 meters. If the result is 4.0 m or more, he survives the jump.
The horizintal distance travelled equals the horizontal jumping velocity component (5.0 cos 15 m/s) times the time it takes to fall 2.5 m. To calculate that time, you need to take into consideration the initial vertical velocity component of 5.0 sin 15 = 1.29 m/s.
With hints, you should be able to proceed. Show your work if futher held is needed.
