Question

When flat bed truck accelerator at 12 m/second square on a level road .the block b is observed to slide along the truck bed at acceleration of 7m/second squared with respect to truck .find coefficient of friction between the block and truck bed?

Answer 1

The relative acceleration of the block is.

12 + 7 = 19 m/s²

Acceleration = coefficient of friction × g

g = 10.

Acceleration = 19

Let the coefficient of friction be m.

19 = m × 10

10m = 19

m = 19/10

m = 1.9

The coefficient of friction is 1.9
