Figure Q1 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. (a) 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 Vj= 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)

Figure Q1 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.
Vj= ( 2 + 0 + 0 + 2 + 1 + 4 ) x 4
Vj= 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.
