an object is shot from the ground at an angle of 35 degrees with a speed of 50m/s. what are the x and y components of its velocity initially at the top of its path and just before it hits the ground?
Vx = 50 cos 35 the whole time
Vy = 50 sin 35 at start and -50 sin 35 at finish
at top, Vx = 50 cos 35 as always and Vy = 0 of course
at ground Vx = 50 cos 35 as always and as we know Vy = -50 sin 35
