Suppose a 71.5 kg gymnast climbs a rope. What is the tension in the rope if she climbs at a constant speed? Number What is the tension in the rope if she accelerates upward at a rate of 1.15 m/s2? Number
A 56.9 kg gymnast climbs a rope at a constant upward acceleration of 0.95 meters/second2. What is the tension in the rope in Newtons, assuming that the rope itself is massless?
6.5 A 75.0-kg painter climbs a ladder that is 2.75 m long leaning against a vertical wall. The ladder makes a 30.0 degree angle with the wall. (a) How much work does gravity do on the painter? (b) Does the answer to part (a) depend on whether the painter climbs at constant speed or accelerates up the ladder?
A gymnast of mass 62.0 kg hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81m/s" for the acceleration of gravity. Part A Calculate the tension T in the rope if the gymnast hangs motionless on the горе. Express your answer in newtons.

A 10 kg monkey climbs up a massless rope that runs over a frictionless tree limb and back down to a 23 kg package on the ground (Fig. 5-54). Bananas Figure 5-54. (a) What is the magnitude of the least acceleration the monkey must have in order to lift the package off the ground? X m/s2 Assume that after the package has been lifted, the monkey stops its climb and holds onto the rope. (b) What is the monkey's acceleration?...
؟ A car (1000 kg) climbs up a hill sloped at 28° while traveling at constant speed of 80 km/hr, what is the power (kW) required for the uphill motion? Select one: a. power 108.7 kW. b. power 89.6 kW. c. power 119.7 kW. d. power 102.3 kW. e. power 95.9 kW. Question 10
A massless vertical rope is used to lower a block of mass 18 kg at constant acceleration 1.1 m/s2 downward. Find the work done by the tension in the rope, in J, after the block is lowered a distance of 54.5 m.
An 92.6-kg climber is scaling the vertical wall of a mountain. His safety rope is made of nylon that, when stretched, behaves like a spring with a spring constant of 1.14 103 N/m. He accidentally slips and falls freely for 0.738 m before the rope runs out of slack. How much is the rope stretched when it breaks his fall and momentarily brings him to rest?
