Question

Michael Jordan makes a throw from the outfield to home plate
in an attempt to throw out the runner on a sacrifice fly. He throws
the ball at 45 m/s and the ball is caught by the catcher on the fly
at approximately the same height as the height at which the ball
left Jordan's hand.

The ball undergoes a horizontal displacement of 100 m in a
time of 2.3 s

a) At what angle did Jordan release the ball?

b) What is the maximum height (above the release height) of
the ball during its flight?

Answer #1

A person throws a ball at an initial angle θ0 = 45° from the
horizontal with an initial speed of v0
= 20 m⋅s-1. The point of release of the ball is at a height d =
2 m above the ground. You may neglect air resistance.
a) How long does it take the ball to reach the highest point of its
trajectory?
b) What was the maximum vertical displacement of the ball?
c) What was the distance of the...

The free throw line in basketball is 4.57 m (15 ft) from the
basket, which is 3.05 m (10 ft) above the floor. A player standing
on the free throw line throws the ball with an initial speed of
7.40 m/s, releasing it at a height of 2.56 m above the floor. At
what angle above the horizontal must the ball be thrown to exactly
hit the basket? Note that most players will use a large initial
angle rather than...

You throw a ball for your dog to fetch. The ball leaves your
hand with a speed of 2 m/s, at an angle of 30◦ to the horizontal,
and from a height of 1.5 m above the ground. The mass of the ball
is 0.5 kg. Neglect air resistance in what follows.
(a) What is the acceleration of the ball while it is in flight?
Report it as a vector, that is, specify magnitude and direction (or
vertical and horizontal...
