Question

You throw a ball straight up with an initial velocity of 18 m/s. It passes a tree branch on the way up at a height of 12.7 m.

(A) How much additional time elapses before the ball passes the tree branch on the way back down (i.e. how much time passes between when the ball is moving upward at a height of 12.7 m to when the ball is moving downward at a height of 12.7 m)?

Correct Answer was 1.76 s.

b) What total distance does the ball travel during this elapsed time? (I havent figured out how to get this answer correct)

Answer #1

I throw a ball straight upward at an initial velocity of +40
m/s. Assuming g is -10 m/s2, (a) how long would it take for the
ball to reach its maximum height before falling back down? (b) what
will its final speed be right before reaching your hand again at
the same height as where you threw it? (c) how does the
acceleration of the ball change as it reaches the top of its path
going 0 m/s?

You throw a ball vertically upward with an initial velocity of
10 m/s from a window located 20 m above the ground. Knowing that
the acceleration of the ball is constant and equal to 9.81 m/s^2
downward (this makes for negative acceleration as upward motion is
positive and downward motion is negative and gravity pulls
downward), determine:
(a) The acceleration at t = 2 s
(b) The equation for velocity (Because you are looking for an
equation for velocity, you...

of 25 m/s at an angle of 50 degrees from the top of a 30m
cliff.
a. Using energy considerations, what is the maximum height of the
ball?
b. What is the magnitude of the velocity when it hits the
ground?

A tennis player tosses a tennis ball straight up and then
catches it after 2.23 s at the same height as the point of
release.
(a) What is the acceleration of the ball while it is in
flight?
magnitude
m/s2
direction
upward, downward, or the magnitude is zero.
(b) What is the velocity of the ball when it reaches its maximum
height?
magnitude
m/s
direction
upward, downward, or the magnitude is zero.
(c) Find the initial velocity of the ball....

A 0.2 kg ball is thrown straight upward at 27.5 m/s from an
initial height of 1.5 meters.
a. As the ball travels upward it passes 10.0 meters in height.
How fast is it rising?
b. How high does it rise before stopping?
c. How long does it rise?
d. How long does it take to hit the ground?
e. How fast is it falling when it hits the ground?

you are standing on the top of the building which is 115 meters
tall. you throw one ball upward at 35.0 m/s and it lands on
theground some time later. you throw a second ball downward from
the same building with velocity of 35.0 m/s and it also hits ground
at a later time which ball will be moving faster when each hits the
ground? support your answer with calculations

1. While standing at the edge of a bridge, you throw a ball
upward with an initial speed of 12 m/s. The ball subsequently falls
to the ground, which is 45 m below the point where the ball leaves
your hand. (a) How much time is the ball in the air? (b) What is
the velocity of the ball when it hits the ground?
2. An object is fired straight up at a speed of 12m/s. Calculate
(a) its maximum...

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...

You throw a tennis ball from a bridge with an initial speed of
14 m/s , at an angle of 14 degrees above the horizontal. You then
throw a baseball from that bridge with an initial speed of 14 m/s ,
at an angle of 17 degrees above the horizontal. Neglecting air
resistance, which of the following statements is true?
The tennis ball and the baseball are both in the air for the
same amount of time.
The tennis ball...

Suppose you throw a ball at 20 m/s at an angle of 60 degrees
from the horizontal from the top of a 40 m building.
a. what is the maximum height?
b. what is the velocity at the highest point?
c. what is the final velocity just as it hits the ground?
d. how far did it travel in the x direction when it hit the
ground?
