Catapult: Details
Operation
Hang a 1 kg mass from the loop of cord shown in the Rear View Detail.
Thread a piece of cord about 20 cm in length through a pulley and tie the cord so it makes a loop. Hang the loop
at the end of the catapult arm.
Pull the catapult arm down so that the pulley/projectile is near the table top and the catapult arm is touching the
front of the base.
Release the catapult arm to send the pulley/projectile on its way.
Question
What happens to the motion of the catapult as the 1-kg mass is allowed to drop?
The small tab at the
end of the Catapult Arm
keeps the cord from
falling off.
