Question

9 of 10> A golfer attempts a birdie putt sending the 0.050-kg ball toward the hole with a speed of 1.7 m/s. Unfortunately, the ball does a "horseshoe" and goes halfway around the rim of the hole. The ball ends up heading back toward the golfer with a speed of 1.3 m/s. Part A If we take the positive direction to be from the golfer to the hole, what is the impulse delivered to the balilby the hole? Express your answer to two significant figures and include appropriate units Value Units Submit Request Answer

Explanation / Answer

Impulse is given by:

Impulse = J

J = dP = m*dV

m = mass of ball = 0.05 kg

Vi = 1.7 m/sec

Vf = -1.3 m/sec

J = m*(Vf - Vi)

J = 0.050*((-1.3) - 1.7)

J = -0.15 kg-m/sec
