Q. A cricket ball is bowled at a speed of 144 km/hr. Assuming the ball diameter is 70 mm and a drag coefficient 0.45, estimate the drag force in newtons which would be acting on the ball.

Q. A hawk flies in a horizontal arc of radius 12.3 m at a constant speed 3.75 m/s.It continues to fly along the same horizontal arc, but increases its speed at the rate of 1.40 m/s2. Find the acceleration in this situation at the moment the hawk's speed is 3.75 m/s.
