A car is stopped aha stop sign and the accelerates at a constant rate to a speed of 40.0 mph in 3.00s. The car then drives at a constant speed for 5.00s and then the driver slams on the brakes because a deer jumped into the road. Assume that the car slows down at a constant rate for 1.35s while it leaves skid marks. How many meters is it from the stop sign to the end of the skid marks?
A ladder of length L=12 m and mass m=45kg leans against a slick wall (there is not friction among ladder and wall). The ladder's upper end is h=9.3 m above the floor. The coefficient of static friction among the ladder and the floor is μ=0.55.
