A \( 1.5 \mathrm{~kg} \) ball drops vertically onto a floor, hitting with a speed of \( 31 \mathrm{~m} / 5 \). It rebounds with an initial speed of \( 9.5 \mathrm{~m} / \mathrm{s} \). (a) What impulse acts on the ball during the contact? (b) If the ball is in contact with the floor for \( 0.0327 \mathrm{~s} \), what is the magnitude of the average force on the floor from the ball? (a) Number Units (b) Number Units
