A cricket ball is observed to travel due east with a speed of 90kmh−1. At that instant its linear momentum is measured to be 5.0kgms−1 directed due east.
(a) Convert the given speed into SI units.
(b) Calculate the mass of the ball.
(c) If the ball is later bowled again at twice the original speed but still along the same line, determine the magnitude and direction of its new momentum.
