A 1200-kg car traveling with a speed of 25 m/s skids to a stop. The car experiences a 1000 N force of friction. Determine the stopping distance of the car.
A shopping cart full of groceries is sitting at the top of a 3.0-m hill. The cart begins to roll until it hits a stump at the bottom of the hill. Upon impact, a 0.5-kg can of peaches flies horizontally out of the shopping cart and hits a parked car with an average force of 100 N. How deep a dent is made in the car (i.e., over what distance does the 100 N force act upon the can of peaches before bringing it to a stop)?
