An industrious chipmunk creates an acorn catapult. This acorn catapult fires a 0.00543 kg acorn at an initial speed of 21.8 m/s. The catapult can be moved to any horizontal distance from the target and it can be set to shoot the acorn at any angle between 14° and 86.6°. The chipmunk will adjust the distance and angle until he gets a shot just right, and he deems a shot to be successful when the target is hit at the moment the acorn reaches its apex d) If the acorn hits the target and bounces back, losing 24.2% of its speed in the collision, what is the magnitude of the change in the acorn's momentum from immediately before the collision to immediately after the collision? e) If the duration of the collision described in part D is 3.01 x 10^-5 s, what is the magnitude of the average force the acorn imparts onto the target?
