A golfer plays a terrible shot, and slices the ball. The ball travelled at a velocity of 44.6 ms^-1, the mass of the golf ball was 45 grams, and the radius of the golf ball was 2.13 cm. The air had a density of 1.20 kg m^-3 Whilst the golfer searched for his ball, his playing partner measured the radius of curvature of the shot to be 185 m. Calculate the rotational speed of the ball when it was struck, in units of s^-1. Answer should be upto two decimal places. (Assume that the ball travels at a constant velocity, and stops instantaneously when it hits the ground)

Density of Solids

The density of a substance refers to how much matter is present in a given amount of space. It is expressed as the ratio of the mass of the substance to its volume.
