Answer:
Actual velocity of the ping-pong ball= 5 m/s
Explanation:
velocity of ping pong ball because of the shot gun= 4 m/s North
velocity added to the ping-pong ball due to the wind=3 m/s
These velocities are perpendicular to each other. so we use Pythagoras theorem to find the resultant velocity of the ping- pong ball
so the actual velocity of the ping-pong ball =V= √4²+3²
V= √25
V= 5 m/s
