A ball is thrown to a receiver of 90kg body mass running at 4m/s North. The ball is thrown at an angle of 45 degrees with an initial velocity of 15m/s. The catch is made in stride (i.e. no angle with direction of motion)
a) Once the ball is caught, what is the change in velocity of the player?
After the catch, a linebacker of 120kg with velocity of 3.5m/s at an angle of 30 degrees South East tackles the receiver and the fall together as one body.
b) What is the total initial momentum in the x and y directions?
c) What is the magnitude of the final velocity of the two players?
d) What direction do they fall.
