1. When the brakes are engaged by the driver of a lightweight truck moving at a speed of 50 km/h, it slides a distance of 20 m before coming to a halt. What would be the skidding distance of the truck if it is travelling at a speed of 90 km/h when the brakes are applied?
A. Assuming the truck is a Toyota Hilux, and the surface is muddy soil (search for a suitable value), what would the skidding distance be if the truck is travelling at a speed of 50 km/h? How would the results differ if a Mazda BT50 ute was used in the same scenario?
B. If we intend for the car to come to a stop within a distance of 17m while travelling (instead of 20m) at 50 km/h and encounter a different surface after 10m, what should the coefficient of friction be for the second surface involved?
