Problem: A car has a mass of 1500 kg. If the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 7000 N.
Problem: If the car is moving at 29 m/s, what is the shortest distance in which the car can stop safely?
I don't know how to get that answer for the above problem. Please help! Thanks.
Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 17apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 57.
