Question

a mass is projected at 50m/s from the top of a 50m high cliff. assuming the mass lands at the bottom, show that the final speed does not depend on the projection angle. Choose 3 projection angels and determine the components of final velocity.

Answer #1

a ball is launched from a cliff with an initial velocity of 15m/s
at an angle of 40degrees above horizontal. if the ball lands 17.5 m
from the base of the cliff. determine the height of the
cliff.

an
object is projected from a cliff with a height of 20.0m with the
speed of 10 m/s and an elevation of 40 degree from the
horizontal.Find the horizontal distance of the projection.

A ball is thrown horizontally with an initial speed of 50m/s
from the top of a building 60m tall
a) How far away from the building will the ball hit the
ground?
b) What is the horizontal component of its velocity when it hits
the ground?
c) Find the magnitude and direction of the velocity when it hits
the ground?

A ball, mass is 8 kg, is thrown from the top of a 30 m cliff
with a velocity of 20 m/s straight up. The ball misses the cliff on
the way down. Ignore air resistance. Use work and conservation of
energy to find the following values.
a. what is the work done by gravity while the ball is in the
air?
b. what is the maximum height of the ball?
c. what is the magnitude of the velocity just...

You are standing on top of a 10-m high cliff. Below you, on the
ground, is a circular target with a radius of 0.5 meters, whose
center is 5 meters from the base of the cliff. On top of the cliff,
and at the edge, is a circular track of radius r. You are going to
drop a 5-kg ball from a height h above the cliff onto the ramp, so
that the ball travels around the track and is...

2) A ball is dropped from rest at the top of a high cliff. It
takes 10.00 seconds for the ball to reach the ground below. Find:
a) the height of the cliff, b) the velocity of the ball hitting the
ground below, c) the time it takes for the ball to fall half of the
cliff's height, and d) the velocity at this halfway point.
(Remember acceleration due to gravity is -9.800 m/s^2).

A
stone is thrown from the top of a cliff with the initial velocity
of 20.0 m/s straight upward. The cliff is 50.0 m high and the stone
just misses the edge of the cliff on its way down. Determine (a)
the time needed for the stone to reach its maximum height; (b) the
maximum height, as measured from the ground; (c) the time needed
for the stone to return to the level of the thrower; (d) the
velocity of...

rock thrown upward with an initial speed of 24.5 m/s
from the top of a 50m tower.
a. what's the rockets velocity the instant it hits the
ground?
b. how long is it in the air?
c. what's the max height above the building the ball
reaches?

A ball of mass 60g is dropped from a height of 3.4m it lands on
top and the surface is not frictionless (Kinetic friction is 0.3).
The hight of the ramp is 1.8m and the ramp is tilted at an angle of
20 degrees.
a) What is the velocity of the ball at the top of the ramp
b) At the bottom of the ramp it collides with and sticks to a
ball of mass 73g. What is the velocity...

A stone is projected at a cliff of height ℎ = 52 ? with an
initial speed of 42.0 ?/? directed at angle ?? = 60.0° above the
horizontal. A. Find the vertical and horizontal components of the
ball’s initial velocity. (2 mark) B. Find the maximum height ? that
the ball reaches. C. Find at what time the stone strikes
?. D. Find the ball velocity (in unit vector nutation)
just before it strikes ?. E. At what horizontal...
