A child weighing 200 N is swinging back and forth on a rope attached to a tree branch. The rope is 3.7 m long and has negligible mass.(a) At the lowest point of the swing, the child is moving with speed 4.0 m/s. What is the tension in the rope at this instant?(b) What is the direction and magnitude of the child’s acceleration at the highest point of the swing when the rope makes an angle ? with the vertical?(c)...

A pendulum has 343 J of kinetic energy at the lowest point in its swing. At the highest point in its swing, it has a height of 5 m. What is the pendulum's mass?
A 20 kg child on a playground swing moves with a speed of 3.8 m/s when the 6.0 m long swing is at its lowest point. What is the angle that the swing makes with thevertical when the child is at the highest point?
A 13 kg child on a playground swing moveswith a speed of 2.9 m/s when the 6.0 mlong swing is at its lowest point. What is the angle that the swingmakes with thevertical when the child is at the highest point?
Tarzan wants to cross a gorge by swinging in an arc from a vertical vine. His arms are capable of exerting a 1400N force on the vine, what is the max. speed he cantolerate at the lowest point of his swing? His mass= 80kg and vine is 5.5m long.
4. A buoy bobs up and down in the lake. The distance between the highest and lowest points is 2 m. takes 4s for the buoy to move from its highest point to its lowest point and back to its highest point a) Model the vertical displacement, v, of the buoy as a SINE FUNCTION of time, t, in seconds. Assume that the buoy is at its maximum atts O s and that the buoy is on its way down...
The maximum speed of a child on a swing is 4.6 m/s. The child's height above the ground is0.70 m at the lowest point in hismotion. How high above the ground is he athis highest point? m
describe your motio when you are on a swing in terms of kinetic and potetial energy. at which point during your motion is each type of energy the greatestPotential energy is hghest when the elevation is highest. Potential energy is lowest (and kinetic energy highest) when the swing is lowest.what do this statement mean Light + LIGHT = NO LIGHTwhat do this statement mean Light + LIGHT = NO LIGHTIn the winter are you letting the cold air in or...
