A body of mass 1 kg experiencing several given external forces moves with a constant velocity along the x axis. If one of the forces, given by (2 $\hat{i}$ ) N ceases to act at $t = 0$ ,

Options:

Answer:

Solution:

For $t < 0$ : constant velocity, so $\sum F = 0$ .

At $t = 0$ the force $2 \hat{i}$ N ceases, so for $t > 0$ : $\sum F = - 2 \hat{i}$ N.

$a = \frac{- 2 i ^}{1} = - 2 \hat{i} m/ s^{2}$ , i.e. $2 m/ s^{2}$ along the negative x axis.
