1N10.35 Roll a car down an incline to smash beer cans. Vary the bumpers to change the impulse. A cart rolls down an incline and smashes a beer can against a brick wall. Four interchangeable bumpers are used to vary the impulse. PIRA 1000 1N10.40 auto collision videodisc 1N10.40 Show segments of the video disc.
Analysis given is for a lab.
A mass on a right angle lever imparts a known variable impulse to a cart on a track and the final velocity is measured. Not many physics instructors will be able to perform these demonstrations. The force created by a momentum change in a fine water stream is calculated using measurements obtained with a large scale impulse balance. The impulse supplied by the counterweight equals the loss of horizontal momentum of a jet of water. The exit velocity of the water jet is then calculated and checked by measuring range.
