A spring-lоаded tоy gun is used tо lаunch а 50 g plastic ball. The spring is compressed by 10 cm as the ball is pushed into the barrel. When the trigger is pulled, the spring is released and shoots the ball back out horizontally. What is the spring constant (k) if the ball’s speed as it leaves the barrel is 2.8 m/s? Assume that friction is negligible.
