I need the The fundamental Work-Energy equation, Analysis of the external work being done, and Detailed expansion of the Work-Energy equation for this situation EXERCISE 6: At a vertical distance d above the ground, a freely-falling skydiver (mass m) opens her parachute. At that moment she has a speed (vertically downward) of vi . The constant tension force exerted on the skydiver by the parachute thereafter is FT. Do a work-energy analysis as if you were preparing to calculate her...

You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of <3,0, 0> m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15...

A dogsled team has four dogs that pull a person and a sled with a combined mass of 100 kg. a) They start from rest and reach a speed of 45 km/h in 2.5 s. What is the net force applied by each dog? Hint: you need to convert 45 km/h to m/s first! b) Suppose each dog can pull with a force of magnitude 150 N. What is the frictional force acting on the sled? Please type in main...

PRACTICE IT Use the worked example above to help you solve this problem. A merry-go-round modeled as a disk of mass M 7.50x 101 kg and radius R 2.40 m is rotating in a horizontal plane about a frictionless vertical axle (see figure) (a) After a student with mass m 84.0 kg jumps onto the merry-go-round, the system's angular speed decreases to 2.10 rad/s. If the student walks slowly from the edge...
