A ball is launched from the ground at an angle of 65∘ above the
horizontal with a velocity of 22m/s. The ball hits the ground some
distance away at a given speed, and bounces back up. When it does
so the amplitude of both the x and y components of its velocity are
half what they were. This repeats with the ball losing half of it’s
speed on each bounce.
a) Sketch the problem.
b) Write the equation of motion...

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

What is the magnitude of its instantaneous velocity the moment
before it hits the ground?
Express your answer in meters per second to two significant
figures.

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.
