KINEMATIC EQUATIONS: What is the ball’s speed when it’s caught by the goalie?

Q: A soccer player kicks the ball toward a goalie that is 29.0 m in front of him. The ball leaves his foot at a speed of 19.5 m/s and at an angle of 33.4° relative to the ground. Find the speed of the ball when the goalie catches it in front of the net.Continue reading “KINEMATIC EQUATIONS: What is the ball’s speed when it’s caught by the goalie?”

ENERGY AND MOMENTUM: ( x ) and ( y ) Vector Components of Motion.

Q: A steel ball of mass 10 kg moves due East at 5.0 m/s. It collides with a rubber ball of mass 5.0 kg moving at 10 m/s due North. After the collision the steel ball moves at an angle of 60° East of North with a speed of 4.0 m/s. What is the velocityContinue reading “ENERGY AND MOMENTUM: ( x ) and ( y ) Vector Components of Motion.”
