Railcar Softball Pitch

Railcar Softball Pitch#

A softball pitcher stands atop a moving railcar which is moving in a straight line with a speed of \(v\_{railcar} = {{ params.v_r }}\ \rm{m/s}\) as illustrated in the figure below.

Part 1#

If the pitcher throws a ball horizontally at a speed of \(v\_{ball/railcar} = {{ params.v_b_r }}\ \rm{m/s}\) relative to the railcar at an angle \(\theta = {{ params.theta }}\ \rm{^{\circ}}\) measured counterclockwise from the direction of motion of the car, what is the speed(\(v\_{ball}\)) of the ball relative to the ground at the instant of projection?

Answer Section#

Please enter the value of \(v\_{ball}\) in \(\rm{m/s}\).

Part 2#

What is the angle \(\alpha\), measured counter-clockwise, that the velocity of the ball relative to the ground makes with the direction of motion of the railcar?

Please enter the value of \(\alpha\) in \(\rm{^{\circ}}\).
