Question 254: Laws of Motion

Question

On the horizontal surface of a truck a block of mass 1 kg is placed (m = 0.6) and truck is moving with acceleration 5 m/sec2 then the frictional force on the block will be

Accepted Answer

Maximum friction force = $$\mu $$mg
= .6 ÃÂ 1 ÃÂ 9.8 = 5.88 N
But here required friction force
= ma = 1 ÃÂ 5 = 5 N

Answer

5 N

Answer

6 N

Answer

5.88 N

Answer

8 N
