Question

A ball is thrown upward with speed of 38.0m/s from top of building 240 m tall: a) How long will it take to reach ground? b)how long will it take for this ball to reach the highest point. c) How long after ball is thrown will it be found 265 m above ground? d) What is velocity of ball as it reaches the ground ? e) what will be the velocity of this ball at the highest point? f) how high above the ground will the ball ball be when it reaches the highest point? g) What is average speed of ball from time thrown until it strikes ground? Suppose that instead of throwing this ball upward it is thrown downward with a speed of 38.0m/s : h) How long will it take for ball to reach ground i) What is speed as it reaches 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.

A ball is thrown vertically upward with a speed of
36.0 m/s.
a) How high does it rise?
b) How long does it take to reach its highest
point?
c) How long does the ball take to hit the ground after
it reaches its highest point?
d) What is its velocity when it returns to the level
from which it started?

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 is thrown vertically upward with a speed of 25.0 m/s from
a height of 30 m from the ground.
How high does it rise from the ground?
How long does it take to reach the maximum height from the point
of projection?
How long does it take to reach to the ground?

A 4.1-kg ball is thrown from the top of a 4-m tall building
(point A) with a speed of 1 m/s at an angle 2 degrees above the
horizontal. If air resistance is negligible, what is the value of
the kinetic energy of the ball as it hits the ground?

A blue ball is thrown upward with an initial speed of 21.2 m/s,
from a height of 0.5 meters above the ground. 2.6 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 11.7 m/s from a height of 25.7 meters above the ground.
The force of gravity due to the earth results in the balls each
having a constant downward acceleration of 9.81
m/s2.
A) What is the speed of the...

2. A ball is thrown straight upward from the window of a
building 40 meters above the ground with an initial velocity of 20
m/s. Calculate
a. The speed of the ball after 1.5 sec.
b. The time needed for ball to reach its maximum height.
c. The maximum height.
d. The time needed for the ball to return back to the same
window which was thrown
e. The time needed for the ball to reach the ground.
f. Final...

A blue ball is thrown upward with an initial speed of 21.4 m/s,
from a height of 0.9 meters above the ground. 2.6 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 9.2 m/s from a height of 25.3 meters above the ground. The
force of gravity due to the earth results in the balls each having
a constant downward acceleration of 9.81 m/s2.
1) How long after the blue ball...

A stone thrown from the top of the building is given an initial
velocity of 8 m/s at an angle of 20.0o below horizontal. It strikes
the ground 3.00 s later. (a) How far horizontally from the base of
the building does the stone strike the ground? (b) Find the height
from which the stone is thrown? (c) How long does it take the ball
to reach a point 10.0 m below the level of launching? (d) What are
the...

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?
