A ping-pong ball is shot straight north from a popgun at 4.0 m/s. The wind is blowing to the west at 3.0 m/s. What is the actual velocity of the ping-pong ball? 7.0 m/s 1.0 m/s

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
