6) Problem 1: A 76-kg man stands on a bathroom scale in an elevator that accelerates upwards from rest to 11 m/s in 2.00 s.
Calculate the scale reading, in newtons, during this process (The scale exerts an upward force on him equal to its reading.)
A 1300-kg car is skidding to a stop along a horizontal surface. The car decelerates from 27 m/s to a rest position in 3 seconds. Assuming negligible air resistance, determine the friction between the car tires and the road surface.
