A basketball (m=0.625 kg) and a baseball (m=145g) are dropped from a height of 2.5 m. For simplicity, assume the basketball and the baseball fall the full height and collide at ground level and that the coefficient of restitution between the floor and the basketball is 0.85. (The coefficient of restitution represents the ratio between the velocity just before collision and the velocity just after collision, the up bounce.) Determine the velocity of the baseball after its collision with the basketball. Assume a perfectly elastic collision between the baseball and the basketball an upward=positive sign convention and g = 10 N/kg.
