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 basketball player is running at a constant speed of 2.5m/s
when he tosses a ball upward with a speed of 6.0m/s. Ignore air
resistance.
1.)Determine the magnitude and direction of the basketball’s
velocity initially, when the ball left the player’s hand.
2.)Determine the vertical displacement of the ball away from the
player’s hands.
3.)Determine the time of flight of the ball given that it
returns to the player’s hand at the same vertical level.
4.)How far does the player...

A ball is thrown vertically upwards with an initial velocity of
10 m/s, from a platform that is at a height of 75 m above the
ground. The ball reaches a maximum height and, on the way down,
misses the platform and falls all the way to the ground. Take the
magnitude of the acceleration due to gravity to be 10 m/s2.
(a) What is the velocity of the ball just before it reaches the
ground?
(b) How many seconds...

A tennis ball rolls off the edge of a tabletop of height 0.830 m
above the floor and strikes the floor at a point a horizontal
distance 1.50 m from the edge of the table. You can ignore air
resistance.
Q1)
Find the time of flight.
Take the free fall acceleration to be g = 9.80 m/s2
Q2)
Find the magnitude of the initial velocity.
Q3)
Find the magnitude of the velocity of the ball just before it
strikes the...

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?

A boy uses a slingshot to launch a pebble straight up into the
air. The pebble reaches a height of 38.0 m above the launch point
1.0 seconds later. Assume air resistance is negligible.
(a) What was the pebble's initial speed (just after leaving the
slingshot)?
42.9 m/s
(b) How much time did it take for the pebble to first reach a
height of 19.0 m above its launch point?
? s
You toss a tennis ball straight upward. At...

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...

A softball player is testing her physics knowledge and tosses a
softball upward from the top of a building. The building is 100 m
tall and the ball starts with a velocity of 10 m/s.
a. What is the maximum height the ball reaches and at what
time?
b. How much time does it take for the ball to go from h=50 m to
h=0 m on the way down?
c. What is the velocity when h=50 m?

A tennis player hits a ball at ground level, giving it an
initial velocity of 26.0m/s at 55.0? above the horizontal.
What is the ball's acceleration at its highest point?
When this ball lands on the court, how far is it from the place
where it was hit?

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?
