A) What friction force is required to stop a block of mass m moving at speed v0, assuming that we want the block to stop over a distance d?
B) Work out a formula for the coefficient of kinetic friction that will achieve this.
C) Evaluate numerical answers to the above two questions assuming the mass of the block is 1000kg, the initial speed is 60 km per hour and the braking distance is 200m.
