where $v = 0$ (final velocity), $u = 4$ m/s (initial velocity), $a = -\frac{5}{2}$ m/s$^2$ (acceleration), and $s$ is the displacement.
Solving for $s$, we get:
A force of 10 N is applied to an object, causing it to move 5 m in the direction of the force. Calculate the work done. dc pandey physics class 11 pdf download part 1 work
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.
First, we need to find the displacement of the object. Using the equation of motion, we get: where $v = 0$ (final velocity), $u =
$$W = 10 \cdot 5 = 50 J$$
Using the formula $W = F \cdot s$, we get: An object of mass 2 kg is moving with a velocity of 4 m/s
$$W = F \cdot s$$
