The two trees in Fig. 9–58 are 7.6 m apart. A backpacker
Chapter 3, Problem 24P(choose chapter or problem)
(II) The two trees in Fig. 9-58 are \(7.6 \mathrm{~m}\) apart. A backpacker is trying to lift his pack out of the reach of bears. Calculate the magnitude of the force \(\overrightarrow{\mathbf{F}}\) that he must exert downward to hold a 19-kg backpack so that the rope sags at its midpoint by (a) \(1.5 \mathrm{~m}\), (b) \(0.15 \mathrm{~m}\)

ANSWER:
Step 1 of 1THe linear momentum is the measurement of quantity of motion of object . Inother words, which is product of mass and velocity of the body. Total momentumis conserved means linear momentum is constant before and after the event.The total momentum of a system after an interaction is equal to the totalmomentum of that system before t
