A batted baseball is hit with a velocity of 44 m/s, starting from an initial height of 4 m. Find how high the ball travels in two cases:
(a) a ball hit directly upward and
(b) a ball hit at an angle of 69° with respect to the horizontal.
Also, find how long the ball stays in the air in each case.

A baseball is thrown from the roof of 23.5 m -tall building with
an initial velocity of magnitude 10.5 m/s and directed at an angle
of 52.4° above the horizontal.
What is the speed of the ball just before it strikes the ground?
Use energy methods and ignore air resistance.

A 5 kg block starting with an initial velocity of 7.69 m/s
travels a distance of x m along a rough surface that has a
coefficient of kinetic friction of μ=0.15. It then travels up a
frictionless ramp at an angle of 17.0⁰ to a height of 1.38 m until
it stops. How far does it travel along the rough surface - what is
the x? (Note there may be more information provided in the
problem statement than you need...
