Projectile Motion Questions :) (1 Viewer)

A projectile is fired horizontally at 150ms-1 from the top of a 196 m high cliff. Calculate:

a) its time of flight
b) its range
c) its velocity on hitting the ground

Thanks for any help guys ! Really appreciated.

A)delta(y)=Ut+.5at^2
196=0xt+.5x9.8xt^2
t^2=196/4.9
t^2=40
t=6.325 seconds

B)range=timesxspeed(x)
range=6.325x150
range=948.75m/s

C) v(Y)=u+at
v(Y)=9.8x6.325
v(Y)=62m/s
use pythag
v^2=62^2+150^2
v=162.3 and need an angle
tan@=62/150
@=22*27*
final velocity
=162.3m/s at 22*27* below horizontal
