Question
Tiger Woods hits a 0.02 kg golf ball, giving it a speed of 25 m/s. What impulse does he impart to the ball?
Solution
Impulse is defined as the change in momentum of an object when the object is acted upon by a force for an interval of time. In this case, the impulse imparted to the golf ball by Tiger Woods can be calculated using the formula:
Impulse = Change in momentum Impulse = Mass * Change in velocity
Given: Mass (m) = 0.02 kg Change in velocity (v) = 25 m/s (since the ball was initially at rest)
Substituting these values into the formula, we get:
Impulse = 0.02 kg * 25 m/s = 0.5 kg*m/s
So, Tiger Woods imparts an impulse of 0.5 kg*m/s to the golf ball.
