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 above the ground is the ball 0.7 seconds after it is kicked?

Answer #1

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 cannonball is shot (from ground level) with an initial
horizontal velocity of 33 m/s and an initial vertical velocity of
25 m/s.
What is the initial speed of the cannonball?
What is the initial angle θ of the cannonball with respect to
the ground?
What is the maximum height the cannonball goes above the
ground?
How far from where it was shot will the cannonball land?
What is the speed of the cannonball 3.6 seconds after it was
shot?...

1. Julie throws a ball to her friend Sarah. The
ball leaves Julie's hand a distance 1.5 meters above the ground
with an initial speed of 21 m/s at an angle 58 degrees; with
respect to the horizontal. Sarah catches the ball 1.5 meters above
the ground.
a. After catching the ball, Sarah throws it back to Julie. The
ball leaves Sarah's hand a distance 1.5 meters above the ground,
and is moving with a speed of 14 m/s when...

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 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 soccer ball is kicked with an initial velocity of 25 m/s at
34 degrees to the horizontal. Find the following:
a. The horizontal and vertical components of the initial
velocity.
b. The highest point reached by the ball.
c. The hang time of the ball.
d. The range of the ball.

ball is kicked with an initial speed of 10 m/s above the
horizontal with an initial angle 30 degree. What is the maximum
height this projectile motion? What is the speed of the ball at its
maximum height? How long does it take the ball to reach the maximum
height? What is the speed of the ball when it hits the ground? What
is the magnitude of the acceleration of the ball when it is at the
maximum height?

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 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 0.415-kg soccer ball is kicked at an initial speed of 32.0 m/s
at an angle of 40.0° to the horizontal. What is the kinetic energy
of the soccer ball when it has reached the apex of its
trajectory?
