(a) Figure Ql shows a lorry delivering a 250 kg crate and the coefficient of static friction between crate and flat bed of the lorry is µs = 0.4. Assuming it starts from rest with a constant acceleration, calculate the fastest time for the driver to reach a final speed of Vs km/h so that the crate does not slip. Use your matrix number to get the value of final speed, Vs. Example; If your matrix number is AD 200214. Vs = ( 2 + 0 + 0 + 2 + 1 + 4 ) x 4 Vs= 36 km/h A car is traveling at 10 km/h when the driver applies brakes and due to the momentum, it skids 3 m before stopping. Predict the skid distance if the same car is traveling at 80 km/h while braking. (b)

A crate, initially traveling horizontally with a speed of 18 ft/s, is made to slide down a 14 ft chute inclined at 35◦. The surface of the chute has a coefficient of kinetic friction μk, and at its lower end, it smoothly lets the crate on to a horizontal trajectory. The horizontal surface at the end of the chute has a coefficient of kinetic friction μk2. Model the crate as a particle, and assume that gravity and the contact forces between the crate and the sliding surface are the only relevant forces. Using conservation law methods, if μk= 0.35, what is the speed with which the crate reaches the bottom of the chute (immediately before the crate’s trajectory becomes horizontal)?
