Thank you

A man stands on the roof of a 19.0 mm -tall building and throws
a rock with a velocity of magnitude 30.0 m/sm/s at an angle of 42.0
∘∘ above the horizontal. You can ignore air resistance.
Calculate the maximum height above the roof reached by the
rock.
Calculate the magnitude of the velocity of the rock just before
it strikes the ground.
Calculate the horizontal distance from the base of the building
to the point where the rock strikes...

A man stands on the roof of a building of height y0 and throws a
rock with a velocity of magnitude v0 at an angle of ? above the
horizontal. You can ignore air resistance. 1)Calculate the
magnitude of the velocity of the rock just before it strikes the
ground. Take free fall acceleration to be g. 2) Calculate the
horizontal distance from the base of the building to the point
where the rock strikes the ground. Take free fall...

Mark is standing of the edge of the roof of a 25.0 m tall
building. He kicks a soccer ball at a velocity of 14.0 m/s at an
angle of 37.0° above the horizontal.
a) How long will the ball be in the air (assume no air
resistance and no buildings in the way to interfere with the path
of the ball)?
b) What will be the maximum height of the ball?
c) With what velocity will the ball hit...

A worker stands on the roof of a 45.0 m high building that is
under construction. He throws a bag of debris giving it an initial
velocity of 12.0 m/s at an angle of 33.0 ∘ from downward direction.
How long is the bag in flight? How far from the building does the
bag land? What is the bag's final speed just before it hits the
ground?

A man throws a ball straight upward with speed 30 m/s from the
top of a building that is 75 m high. Ignore air resistance and
choose the vertical y-axis to be positive downward with
origin at the point of throw (top of the building).
Represent the initial velocity and the acceleration vectors in
the reference y-axis above.
Find the maximum height the ball reaches with respect to the
ground.
How long does it take the ball to reach the...

A worker stands on the roof of a 45.0m high building that is
under construction. He throws a bag of debris giving it an initial
velocity 12m/s of at an angle of 33.0 from downward direction.
a. How long is the bag in flight?
b. How far from the building does the bag land?
c. What is the bag's final speed just before it hits the
ground?

A boy standing on top of a building throws a small ball from a
height of H1 = 37.0 m. (See figure.) The ball leaves
with a speed of 24.5 m/s, at an angle of 53.0 degrees from the
horizontal, and lands on a building with a height of H2
= 16.0 m. Calculate for how long the ball is in the air. (Neglect
air friction, and use g = 9.81 m/s2.)

(a) A projectile is fired off the roof of a 15m tall building,
with a speed of 17 m/s and angle of 40o above the horizontal. What
is the maximum height, above the ground, of the projectile?
(b) A projectile is fired off the roof of a 15m tall building,
with a speed of 17 m/s and angle of 40o above the horizontal. How
far away from the building does the projectile land?

A worker kicks a flat rock lying on a roof. The rock slides up
the incline 10.0 m to the apex of the roof, and flies off the roof
as a projectile. What maximum height (in m) does the rock attain?
Assume air resistance is negligible, vi = 15.0 m/s, μk = 0.480, and
that the roof makes an angle of θ = 43.5° with the horizontal.
(Assume the worker is standing at y = 0 when the rock is...
