Question

A block slides along a rough table and is brought to rest after travelling a distance of 2.7m. The frictional force is assumed constant at 3.8 N. Find the work done by the frictional force.

Answer 1

The workdone by the Frictional force is 10. 26 Joules.

Step-by-step explanation:

Parameters: Frictional force = 3.8 N

Distance = 2.7m

Workdone = ? Joules

Workdone = Frictional force × Distance travelled

= 3. 8 × 2. 7

= 10.26 Joules.

The workdone by the frictional force when brought to rest after travelling a distance of 2. 7m is 10. 26 Joules.
