Question

A block of mass 2kg is pulled by a force of 10N on a surface with μk\=0.3. What is its acceleration? (Take g\=10m/s2)

Options

Choose one · Correct answer highlighted

Explanation

Net force Fnet=F−fk, where fk=μkN. As per NCERT Chapter 3, equations v=u+at, s=ut+½at², v²=u²+2as describe uniformly accelerated motion. Applying correct signs and units gives 2 m/s² as the result, so option B is correct.
