Q1 (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 µ; = 0.4. Assuming it starts from rest with a constant acceleration, calculate the fastest time for the driver to reach a final speed of Vz km/h so that the crate does not slip. Use your matrix number to get the value of final speed, Vs.| V;= (2+ 0 + 0 + 2+ 1 + 0 ) x 4 Vy= 20 km/h

Q1 (a) 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 us = 0.4. Assuming it starts from rest with a constant acceleration, calculate the fastest time for the driver to reach a final speed of V; km/h so that the crate does not slip. Use your matrix number to get the value of final speed, Vs| V;= (2 +0+ 0+ 2 + 1 + 0)x 4 V= 20 kon/h
