$$W = 10 \cdot 5 = 50 J$$

First, we need to find the displacement of the object. Using the equation of motion, we get: dc pandey physics class 11 pdf download part 1 work

$$W = \Delta KE$$

where $v = 0$ (final velocity), $u = 4$ m/s (initial velocity), $a = -\frac{5}{2}$ m/s$^2$ (acceleration), and $s$ is the displacement. $$W = 10 \cdot 5 = 50 J$$
