Question

A block of mass 1.5 kg rests on a rough horizontal surface. A horizontal force applied to the block
increases uniformly from 0 to 15 N 5 seconds. Determine displacement of the block after 5 seconds.
Use static coefficient of friction = 0.6 and kinetic coefficient of friction= 0.5 and g = 10 m/s2.​

Answer 1

Answer:

Consider,

Force applied =F

Friction force =f

F−f=ma

1.2g−(0.3)(1.5)g=1.5a

Therefore, a=0.5g

Hence, the acceleration produce 0.5g
