A block of mass 2 kg is given a push horizontally and then the
block starts sliding over a horizontal plane. The graph shows the
velocity time graph of the motion. The co-efficient of friction between
the plane and the block is

Show answer and solution

a = slope of v-t graph = - 2 m/s2
∴ Ft = μmg = m × 2
⇒μ × 2 × 10 = 2 × 2 ⇒ μ = 0.2
