Question

A baseball player throws a ball into the air with an initial velocity of 22 m/s [up].

a) How high up does the ball go?

b) If she catches the ball from the same height that she threw it, how long was the ball in the air?

Answer #1

Initial Velocity, u = 22 m/s

Final Velocity, v = 0 m/s

Acceleration due to gravity, g = - 9.8 m/s2 ( beacuse it is moving upwards )

a)

Using equation of Motion :

Height reached,

b)

Using equation of Motion :

Time taken to reached maximum height,

Time for which the ball was in the air,

Rodney throws a ball upward into the air with an initial
velocity of 18 m/s. How high does it go and how long the ball is in
the air before it comes back to his hand?

A girl throws a ball straight up into the air with the initial
velocity v0 = 18.0 m/s. At a certain point, the ball falls back
into the girl's hands.
a) What is the highest height the ball will reach?
b) How long is the ball in the open air?
c) What is the velocity of the ball just before it hits
again?

A batted baseball is hit with a velocity of 42.1 m/s, starting
from an initial height of 7 m. Find how high the ball travels in
two cases:
(a) a ball hit directly upward and
(b) a ball hit at an angle of 75° with respect to the
horizontal.
Also find how long the ball stays in the air in each case.
case A
case b

A pitcher throws a 0.19-kg baseball ball with a velocity
of 42 m/s. It is struck by the bat with an average force of 700 N,
which results in a velocity of 28 m/s in the opposite direction
from the original velocity. How long were the bat and ball were in
contact?

A basketball player throws a basketball horizontally with an
initial velocity of 5 m/s at an initial height of 1.6 meters.
If the basketball lands on the ground, how far (in meters) does
the basketball land from the player's feet? Round your answer to
the nearest hundredth (0.01)

A baseball pitcher throws a pitch with an initial velocity of
46.0 m/s, directed horizontally. How far does the ball drop
vertically by the time it crosses the plate 18.0 m away?

1. A baseball player hits a ball that reaches a maximum height
of 16.9 m and lands 98 m away. The ball contacts the bat 1.25m
above the ground and has a launch angle of 30?? .
a. What is the initial velocity?
b. How long is the ball in the air?
c. Determine the velocity vector, in vector notation, when the
ball strikes the
ground.

A ball is thrown in the air from player A to player B. When
player A throws the ball, player B is 18 m away from player A and
runs away from player A with an average velocity of 7 m/s for 1.5
seconds. Unfortunately, player B ends up being 3 m short of where
the ball should be caught. A) Draw and label a diagram of the
physical situation (include the trajectory). B) Determine the
horizontal distance that the...

Nicholas throws a ball with an initial speed of 10.00 m/s at
an angle of 58° above the horizontal. The ball leaves her hand 0.88
m above the ground and experience negligible air resistance.
(a)How far from where the child is standing does the ball hit
the ground?
(b)How long is the ball in flight before it hits the
ground?
(c)What is the magnitude of the ball's velocity just before
it hits the ground?
(d)At what angle below the horizontal...

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?
