Q3. Momentum 10 points A 0.8m-long slingshot spins a 75g pebble at 1900"/s before release. a) What is the velocity of the pebble upon release? (4pts) b] What is the momentum of the pebble upon release? (2pts) c) How far will the pebble travel in 1.5 seconds? (2pts) d) Why must conversions from angular to linear velocity be done in terms of radians instead of degrees? (2pts) Q4.
