Q1Physical Quantities and MeasurementKinematicsForcesFree sample

Fig. 1.1 shows a cricket ball as it comes into contact with a cricket bat.

Fig. 1.1

The cricket ball has a mass of $0.16\ \text{kg}$ and it hits the bat with a speed of $25\ \text{m / s}$ . After being in contact with the bat for $0.0013\ \text{s}$ , the ball rebounds with a speed of $22\ \text{m / s}$ in the direction exactly opposite to its original direction.

(a)

State the difference between speed and velocity.

______

(b)

Calculate

(i)
