29. Jonathan is riding a bicycle and encounters a hill of heightAMT 7.30 m. At the base of the hill, he is traveling at 6.00 m/s.When he reaches the top of the hill, he is traveling at1.00 m/s. Jonathan and his bicycle together have a massof 85.0 kg. Ignore friction in the bicycle mechanism andbetween the bicycle tires and the road. (a) What is thetotal external work done on the system of Jonathan andthe bicycle between the time he starts up the hill andthe time he reaches the top? (b) What is the change inpotential energy stored in Jonathan's body during this pro-cess? (c) How much work does Jonathan do on the bicyclepedals within the Jonathan-bicycle-Earth system duringthis process?

Three skydivers are plummeting earthward. They are initially holding onto each other, but then push apart. Two skydivers of mass 70 and 80 kg gain horizontal velocities of 1.2 m/s north and 1.4 m/s southeast, respectively. What is the horizontal velocity of the third skydiver, whose mass is 55 kg?
Consider the length of the boat as the x-axis with the origin at its left end. The positions of the persons are xa= 1.0 m, xb= 2.5 m, xc= 3.0 m. According to the problem, the three persons almost have the same mass: Ma=Mb=Mc=M, where is the center of the mass in the boat?
A hiker inspects a tree frog sitting on a small stick in his hand.Suddenly startled, the hiker drops the stick from rest at aheight of 1.85 m above the ground and, at the same instant,the frog leaps vertically upward, pushing the stick down sothat it hits the ground 0.450 s later. Find the height of the frogat the instant the stick hits the ground if the frog and the stickhave masses of 7.25 g and 4.50 g, respectively. (Hint: Find thecenter-of-mass height at t = 0.450 s for the frog–stick systemand then use the definition of center of mass to solve for thefrog’s height.)
