motion
a projectile is shot from the edge of a cliff 115 m above ground level with an initial speed of 65.0 m at an angle of 35 with the horizontal.
(a) Determine the time taken by the projectile to hit point P at ground level.
(b) Determine the distance X of point P from the base of the vertical cliff
(c) At the instant just before the projectile hits point P, find the horizonal and the vertical components of its velocity
(d) the magnitude of the velocity
(e) the angle made by the velocity with the horizonal
(f) find the max height above the cliff top reached by the projectile
My attempt
(a) t1 = vy/g = 3.8 sec
t2 = square root of (2 X s / g) = 6.2
for s i did s= 115 + 37 X 3.8 + (1/2)(9.81)3.8^2
s= 185
T = t1 + t2 = 3.8 + 6.2 = 10
(b) distance = t X Vx
10 X 53 = 531
(f) is s = 185
and im completely lost on c , d, e
