Academics

1. A 76- kg crate is at rest on the floor. It takes a minimum horizontal force of 350 N to make the crate slide. Calculate the coefficient of static friction between the crate and the floor.

2. A 1500 kg car is headed directly for a brick wall when the driver realizes the danger and slams on the brakes. The car's initial speed is 32 m/s, and the coefficient of kinetic friction between the tires and the road is 0.55. Determine how far the car travels while skidding to a stop. Assume it travels in a straight line.
