Question

A ball is kicked from a location < 5, 0, -7> m (on the ground) with initial velocity <-8, 19.0, -2> m/s. The ball’s speed is low enough that air resistance is negligible. (a) What is the velocity of the ball 0.5 s after being kicked? (Use the Momentum Principle!) Please explain!

A
soccer ball is kicked with an initial speed of 15 m/s at an angle
of 53 degrees above the horizontal from the top of a building. If
air resistance is negligible then how far does the ball travel
horizontally from the edge of building by the time it hits the
ground ?

A soccer ball is kicked with an initial horizontal velocity of
15 m/s and an initial vertical velocity of 15 m/s.
What is the initial speed of the ball?
What is the initial angle θθ of the ball with respect to the
ground?
What is the maximum height the ball goes above the ground?
How far from where it was kicked will the ball land?
What is the speed of the ball 0.7 seconds after it was
kicked?
How high...

A soccer ball is kicked from the ground into The air with a
velocity of 25 m/s at 45 degrees above horizontal. To the nearest
meter, how high did the ball fly? How far did the ball travel
before hitting the ground again assuming there was no wind
resistance? (round to the nearest meter)

a
ball is kicked off a cliff with a velocity if 13.99 m/s at an angle
of 35 deg above the horizontal. the height of the cliff is 15.0m.
ignoring air resistance.
a)whats the horizontal velocity of the ball?
b)how long is the ball in the air?
c)what speed does the ball hit the ground with

A
soccer ball is kicked with an initial horiztontal velocity of +15
m/s and an initial vertical velocity of +8 m/s. Assuming that
projection and landing heights are the same and neglecting air
resistance, answer the following.
a)The balls horizontal velocity 0.5 seconds into its
flight:
b)The balls horizontal velocity midway through its
flight:
c)The balls horizontal velocity immediately before contact
with the ground:
d)The balls vertical velocity at the apex of the flight:
e)the balls vertical velocity midway through...

The velocity of a ball changes from <8, -7, 0> m/s to
<7.95, -7.24, 0> m/s in 0.02 s, due to the gravitational
attraction of the Earth and to air resistance. The mass of the ball
is 250 grams. (a) What is the acceleration of the ball? (b) What is
the rate of change of momentum of the ball? (c) What is the net
force acting on the ball?
Please explain. Thank you.

A ball is kicked with an initial velocity of 20 m/s in the
horizontal direction and 11 m/s in the vertical direction. (Assume
the ball is kicked from the ground.) At what speed (in m/s) does
the ball hit the ground?

A
ball kicked from ground level at an initial velocity of 75 m/s and
an angle theta with the ground reaches a horizontal distance of 500
meters
A.) What is the size of angle theta?
B.) What is time of flight of the ball?
please show work would help each steps

A ball is kicked with
an initial velocity of 20 m/s at an angle of 30o above
the horizontal. Calculate the following:
At what speed does the ball hit the ground?
For how long does the ball remain in the air?
What maximum height is attained by the ball?

A football is kicked from ground level with an initial velocity
of 24.2 m/s at angle of 51.0° above the horizontal. How long, in
seconds, is the football in the air before it hits the ground?
Ignore air resistance.
