After 4.5 seconds of flight, the soccer ball hit the horizontal
distance 46m from the excavation site. What was his expectation
speed (size and direction), or given to him by the player on
arrival, at a height of 1.5 m above the ground?
A soccer player kicks a ball at an angle of 36◦ from the direct
horizontal with an initial speed of 15.5 m/s. Assuming that the
ball moves in a two-dimensional plane, find its maximum height and
its velocity when it strikes the ground.
3) A soccer ball is kicked with an initial horizontal speed of 8
m/s and an initial vertical speed of 6
m/s. Identify the following quantities and include one short
sentence to explain your answer using
the concepts of projectile motion (no calculations are
necessary). Assume that projection and
landing height are the same and neglecting air resistance (4
pts):
a) The ball’s horizontal speed 0.5 seconds into its flight
is:
because:
b) The ball’s horizontal speed midway through its...

A ball is placed at the top of a hill and then released. After 5
seconds it has a speed of 20 m/s. What is the average acceleration
of the ball? A) 10 m/s^2 B) 0 m/s^2 C) 100 m D)5 m/s^2 E) 4
m/s^2
a
ball is propelled vertically upward with initial velocity as
15meter/seconds. distance is set up as s(t)=15t-4.9t^2. When will
the object be 5 meters above the ground, when will it strike the
ground, and will the object reach a height of 90 meters? Please
include all work thank ylu so much in advance!
A ball of mass 2.00 kg, resting on a horizontal frictionless
surface, gets hit by another ball of mass 1.50 kg moving in the
+x-direction with a speed 4.00 m/s. After the collision, the 1.50
kg ball has a speed of 2.00 m/s at an angle 60.0° counterclockwise
from the +x-direction.
a) Find the velocity of the 2.00 kg ball just after the
collision. Express your answer in vector form.
b) Compute the percent of kinetic energy lost in the...
Assume that the height of a ball in feet off of the ground after
t seconds is given by the function h(t).
If you know the following about the function h and its
derivative
1. h(5) = 250 ft
2. h'(1) = 15 ft/sec
3. h'(5) = 0 ft/sec
4. h'(6) = -2 ft/sec
Recall that h'(t) is the derivative of h at seconds, and h(t) is
the function h evaluated at t seconds.
Explain what each of the 4...
Suppose a ball has a maximum height of 24 feet after 11 seconds
of travel. This same ball will have a height of 8 feet after 20
seconds of travel. Find
Upper H left parenthesis Upper T right parenthesis equals AT
squared plus BT plus Upper C commaH(T)=AT2+BT+C,
where H(T) is the height of the ball in inches after T seconds.

A soccer ball is kicked from the top of one building with a
height of H1 = 30.1 m to another building with a height
of H2 = 10.8 m. (It is not a very smart idea to play
soccer on the roof of tall buildings.)
The ball is kicked with a speed of v0 = 19.3 m/s at
an angle of θ = 74.0° with respect to the horizontal. The mass of a
size 5 soccer ball is m...
