Compute all parts of given problem:
Problem: A spring gun fires a ball horizontally at 14 m/s. It is mounted on a flatcar moving in a straight line at 25 m/s.
Part A: Relative to the ground, what is the horizontal speed of the ball when the gun is aimed forward?
m/s
Part B: Relative to the ground, what is the horizontal speed of the ball when the gun is aimed backward?
I need help to find the horizontal speed of the ball when the gun is aimed forward.
