The force-time $(F -t) $ curve of a particle executing linear motion is as shown in the figure. The momentum acquired by the particle in time interval from zero to $8$ second will be ........... $N-s$

A$-2$

B$+ 4$

C$6$

D$0$

Solution

(d)Momentum acquired by the particle is numerically equal to area enclosed between the $F-t $ curve and time axis. For the given diagram area in upper half is positive and in lower half is negative (and equal to upper half), so net area is zero. Hence the momentum acquired by the particle will be zero.

A light string fixed at one end to a clamp on ground passes over a fixed pulley and hangs at the other side. It makes an angle of $30^o$ with the ground. A monkey of mass $5\,kg$ climbs up the rope. The clamp can tolerate a vertical force of $40\,N$ only. The maximum acceleration in upward direction with which the monkey can climb safely is ………… $m/s^2$ (neglect friction and take $g = 10\, m/s^2$)
