If it takes the driver from the last question 0.2 seconds to slow down from 5m/s to 3m/s in her 1,000 kg car, how much force was applied to the car?

The man fires an 80 g arrow so that it is moving at 80 m/s when it hits and embeds in a 8.0 kg block resting on ice. how far will the block slide on the ice before stopping? a 7.1 n friction force opposes its motion.
