Question

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.

Answer #1

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...

A ball is thrown toward a cliff of height h with a speed of 33
m/s and an angle of 60 ? above horizontal. It lands on the edge of
the cliff 3.7 s later.
How high is the cliff?
What was the maximum height of the ball?
What is the ball's impact speed?

A ball is thrown toward a cliff of height h with a
speed of 30 m/s and an angle of 60∘ above horizontal. It lands on
the edge of the cliff 3.0 s later.
a) How high is the cliff?
b) What was the maximum height of the ball?
c) What is the ball's impact speed?

An
object is thrown upwards from certain level with a speed of
20.0m/s. A person at a window observes the object going up, and
when it returns down he catches it at point 5.00m over the starting
level. Determine the time of the object in the air.

A mountain climber throws a carabiner off the vertical face of a
cliff from a height h=27.2 m above the ground. The carabiner lands
a horizontal distance of 36.3 m away from the base of the cliff. If
the carabiner was thrown with an initial velocity that is
horizontal, what was its initial speed when thrown?

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.

A mountain climber throws a carabiner off the vertical face of a
cliff from a height h=27.7 m above the ground. The carabiner lands
a horizontal distance of 45.8 m away from the base of the cliff. If
the carabiner was thrown with an initial velocity that is
horizontal, what was its initial speed when thrown? Select one:

A ball is thrown toward a cliff of height h with a speed of
30m/s and an angle of 60 degrees above horizontal. it lands on the
edge of the cliff 4 seconds later.
A) How high is the cliff?
B)What is the maximum height of the ball?
C)What is the ball's impact speed?

On a level football field a football is projected from ground
level. It has speed 8.0 m/s when it is at its maximum height. It
travels a horizontal distance of 70.0 m. Neglect air
resistance. How long is the ball in the air?

A boy kicks a rock off a cliff with a speed of 18.2 m/s at an
angle of 54.0° above the horizontal. The rock hits the ground 5.21
s after it was kicked.
How high is the cliff?
What is the speed of the rock right before it hits the
ground?
What is the maximum height of the rock in the air, measured from
the top of the cliff
