Final answer:
The impulse on the ball is calculated by multiplying the force by the time the force is applied, resulting in an impulse of 1 N·s.
Step-by-step explanation:
The student asked about the impulse exerted on a ball by a cricket bat which hits with a force of 10 N for 0.1 seconds. Impulse in physics is a measure of the change in momentum of an object when it is acted upon by a force over a period of time. It is calculated using the formula: impulse (I) = Force (F) × Time (t).
To find the impulse on the ball, we simply multiply the force applied by the time duration of the force. So, the impulse I = 10 N × 0.1 s = 1 N·s (newton-seconds).
The impulse is provided in the same direction as the force applied by the cricket bat, which in this case, would typically be horizontally forwards from the batsman's perspective.
