Solving for $s$, we get:
An object of mass 2 kg is moving with a velocity of 4 m/s. A force of 5 N is applied in the opposite direction of motion, causing it to slow down. Calculate the work done by the force.
Using the formula $W = F \cdot s$, we get: dc pandey physics class 11 pdf download part 1 work
Now, we can calculate the work done:
$$W = \Delta KE$$
$$v^2 = u^2 + 2as$$
$$s = \frac{u^2}{2a} = \frac{4^2}{2 \cdot \frac{5}{2}} = \frac{16}{5} m$$ Solving for $s$, we get: An object of
$$W = 10 \cdot 5 = 50 J$$
