A stone is thrown from ground level at an angle of θ above the
horizontal such that the ratio of the x-component of its initial
velocity to the y-component of its initial velocity is 2. The stone
strikes a wall 6 m away and at a height of 2 m above the ground.
Calculate the initial speed of the stone
A baseball leaves the bat 1.5m above the ground traveling at
100mph at an angle of 27 degrees above the horizontal. There is a
3.1m high fence 14m a. Assuming air resistance is negligible on
which side of the fence does the baseball first hit? b. How far
from the fence does it first make impact?

A ball is thrown at a 60.0° angle above the horizontal across
level ground. It is released from a height of 2.00 m above the
ground with a speed of 16.0 m/s. How long does the ball remain in
the air before striking the ground?
Please explain why variables are positive and negative in
relation to direction positive or negative.
If Emily throws the ball at an angle of 30∘ below the horizontal
with a speed of 14m/s, how far from the base of the dorm should
Allison stand to catch the ball? Assume the vertical distance
between where Emily releases the ball and Allison catches it is
8.0m.
A
projectile is launched at an angle of 60 degrees to the horizontal
from 6.5ft above the ground at an initial speed of 100 ft/sec.
Assume the x-axis is horizontal, the positive y axis is vertical
(opposite g), the ground is horizontal, and the only gravitational
force acta on the object. Answer parts A through D.
A) Find the velocity - v(t) and position - r(t) vectors for t
greater than or equal to 0.
B) Graph the trajectory

A shot putter threw a shot at an angle of 43o above the
horizontal from a height of 2.0 m above the ground. The shot
traveled 19.0 m horizontally from the launch position. (a) What was
the initial speed of the shot when it left the shot putter’s hand?
(b) How long was the shot in the air? {13.0 m/s, 2.0 s}
An object is launched from 2.3 meters above the ground with a 60
degree angle with the horizontal the ball collides with the earth
at a distance of 20.5 meters
A) Calculate the maximum height
B) Calculate the initial speed.
C) Calculate the speed before impact
A
ball is launched at an angle of 33.4 degrees up from the
horizontal, with a muzzle velocity of 6.5 meters per second, from a
launch point which is 1 meters above the floor. How far
horizontally (in meters) from the launcher will it land on the
floor? Use 9.82 meters per second for “g”.
A projectile is fried at an angle of 58° above the horizontal at
a speed of 100 m/s.
