A garbage cart full of garbage, is there at the top of a 2.0-m hill. The cart begins to roll until it hits a stump at the bottom of the hill. Upon impact, a 0.25-kg can of peaches flies horizontally out of the garbage cart. The entire kinetic energy of the cart is transferred to the can and it hits a parked car with an average force of 500 N. How deep a dent is made in the car (that is over what distance the 500 N force act upon the can of peaches before bringing it to a stop)? (Neglect the effect of friction while the cart is rolling down the hill.) |
