A 65kg man runs towards a river and aims to hold on to a 3-m rope that is tied on a tree. He runs at an initial velocity of 5.5 m/s with a uniform acceleration of 35 m/s? and a running distance of 5-m before he grabs the rope. During running, he experiences an opposing horizontal air resistance of 10 N. Then, he swings over the river using the 3-m rope with a constant speed before letting go of the rope. Determine the following: (a) the velocity of the man upon grabbing the rope, (b) the time he spent during running before reaching the rope, (c) traction force during running, and (d) the tension in the rope just before letting it go. e= 45 3m 大 5m

A box with mass m sits at the bottom of a long ramp thatis sloped upward at an angle a above the horizontal. You give the boxa quick shove, and after it leaves your hands it is moving up the rampwith an initial speed v0. The box travels a distance d up the ramp andthen slides back down. When it returns to its starting point, the speedof the box is half the speed it started with; it has speed v0 /2. What isthe coefficient of kinetic friction between the box and the ramp? (Youranswer should depend on only a.)
