Question

A ball is thrown up onto a roof, landing 3.10 s later at height
*h* = 18.0 m above the release level. The ball's path just
before landing is angled at *θ* = 63.0˚ with the roof.
**(a)** Find the horizontal distance *d* it
travels. (*Hint:* One way is to reverse the motion, as if it
is on a video.) What are the **(b)** magnitude and
**(c)** angle (relative to the horizontal) of the
ball's initial velocity?

Answer #1

In the figure here, a ball is thrown up onto a roof, landing
3.20 s later at height h = 21.0 m above the release level.
The ball's path just before landing is angled at ? = 67.0?
with the roof. (a) Find the horizontal distance
d it travels. (Hint: One way is to reverse the
motion, as if it is on a video.) What are the (b)
magnitude and (c) angle (relative to the
horizontal) of the ball's initial...

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?

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?

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?

In the figure, a baseball is hit at a height h = 1.10 m and then
caught at the same height. It travels alongside a wall, moving up
past the top of the wall 1.3 s after it is hit and then down past
the top of the wall 3.4 s later, at distance D = 55 m farther along
the wall. (a) What horizontal distance is traveled by the ball from
hit to catch? What are the (b) magnitude...

A
ball is thrown from the roof of a building. The initial velocity
vector is at an angle of 53.0° above the horizontal. It is at
maximum height in 1.04 seconds. Express all vectors in terms of
unit vectors i and j. The ball strikes the ground at a horizontal
distance from the building of 33.1 meters.
a.) What is the vertical velocity (vector) at t=1.04
seconds?
b.) What is the initial vertical velocity (vector)?
c) What is the inital...

A ball is thrown with an initial speed vi at an angle θi with
the horizontal. The horizontal range of the ball is R, and the ball
reaches a maximum height R/8. In terms of R and g, find the
following.
(a) the time interval during which the ball is in motion t =
(b) the ball's speed at the peak of its path v =
(c) the initial vertical component of its velocity yi =
(d)...

A ball is thrown toward a cliff of height h with a
speed of 25m/s and an angle of 60? above horizontal. It lands on
the edge of the cliff 4.0s later.

A ball is thrown straight upward and returns to the thrower's
hand after 3.10 s in the air. A second ball thrown at an angle of
33.0° with the horizontal reaches the same maximum height as the
first ball.
(a) At what speed was the first ball thrown?
m/s
(b) At what speed was the second ball thrown?
m/s
