Question

A canon is located at the edge of a cliff of height 115m. The canon ball is fired with an initial velocity of 65.0m/s at an angle of 35 degrees with the horizontal. By indicating the coordinate axis (increasing values of y). Calculate the vertical velocity of the canon with which it will strike point P. Calculate the total velocity of the canon with which it will strike point P. Calculate the total horizontal distance (x) travelled by the canon ball.

A projectile is shot from the edge of a cliff 115 m m above
ground level with an initial speed of v0 v 0 = 54 m/s m / s at an
angle of 35.0∘
A) Determine the time taken by the projectile to hit point P P
at ground level.
B)Determine the distance XX of point PP from the base of the
vertical cliff.

A projectile is launched from point O at the edge of a cliff by
the sea, with initial speed of 22 m/sm/s at an angle of 45° above
the horizontal. The projectile rises and then falls into the sea at
point P. The projectile travels a total horizonal distance D = 38
mm from the cliff. Ignore air resistance.
a) If you want to maximize the horizontal range, how should you
adjust the launch angle?
b) Calculate the time the...

a
ball is kicked off a cliff with a velocity if 13.99 m/s at an angle
of 35 deg above the horizontal. the height of the cliff is 15.0m.
ignoring air resistance.
a)whats the horizontal velocity of the ball?
b)how long is the ball in the air?
c)what speed does the ball hit the ground with

3) A ball is thrown leftward from the left edge
of a roof at height “h” above the ground. The ball hits the ground
1.5 sec later at a distance d = 25 m from the building and at an
angle θ = 60° with the horizontal.
a)
What is the value of “h”?
b)
What is the magnitude of the initial velocity?
c)
What is the angle of the initial velocity?
