Question

A ball is thrown upward from ground level at 25 m/s. At the same instant, a second ball is dropped from rest from a building 15 m high. How high above the ground will the two balls be when they are at the same height? Please break it out to where it makes sense. Thank you!

Answer #1

A ball is thrown vertically upward from a window that is 3.6 m
above the ground. The ball's initial speed is 2.8 m/s and the
acceleration due to gravity is 9.8 m/s^2.
a) What is the ball's speed when it hits the ground?
b) How long after the first ball is thrown should a second ball
be simply dropped from the same window so that both balls hit the
ground at the same time?

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...

A ball with mass m kg is thrown upward with initial velocity 16
m/s from the roof of a building 28 m high. Neglect air resistance.
Use 9.8 m/s2. Round your answers to one decimal place. (a) Find the
maximum height above the ground that the ball reaches. meters (b)
Assuming that the ball misses the building on the way down, find
the time that it hits the ground.

Bob drops a ball from rest out the window of a building. At the
very same instant Phyllis releases a ball upward with an initial
speed of 11.0 m/s from a point 20.0 m directly below Bob.
(a) At what height above Phyllis do the balls collide?
(b) Is the ball thrown by Phyllis moving upward or downward when
the collision occurs? Explain

A ball is dropped from rest from the top of a building with
height 50 meters. At the same instant, you throw a ball upward from
ground level carefully aimed to hit the falling ball. If the
initial speed of your throw is 19 m/s, then the two balls collide
at a height above the ground equal to:
a) 4.50 m b) 7.61 m c) 12.2 m d) 16.1 m e) 2.15 m

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 with mass 1/9.8 kg is thrown upward with initial velocity
20 m/s from the roof of a building 30 m high. Assume that the force
of air resistance (drag force) is (v^2)/1225. Find the maximum
height above the ground that the ball reaches. (Hint: ﬁnd the
velocity v(t) ﬁrst, then ﬁnd the height x(t).)

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?

At t = 0, Ball 1 is dropped from the top of a 19 mm-high
building. At the same instant Ball 2 is thrown straight up from the
base of the building with an initial velocity of +12 m/sm/s. Assume
that Ball 1 starts from rest and that air friction can be ignored.
At what height will the two balls pass each other?
What is the velocity of each ball at the moment they are at the
same height?
Express...

Ball 1 is thrown vertically upwards at 8 m/s from a height of 30
meters from the side a building. A second ball is thrown upwards
from the ground (height of 0 m) 0.39 seconds after the ball 1 is
thrown upwards. With what speed, in m/s, does the second ball need
to be thrown such that it collides with ball 1 when ball 1 is 8
meters above the ground?
