- A 61.8-kg skateboarder starts out with a speed of 1.75 m/s. He does 80.4 J of work on himself by pushing with his feet against the ground. In addition, friction does -221 J of work on him. In both cases, the forces doing the work are non-conservative. The final speed of the skateboarder is 9.19 m/s. (a) Calculate the change (PEF - PEo) in the gravitational potential energy. (b) How much has the vertical height of the skater changed? Give the absolute value. (a) Number (b) Number i Units UnitsIn the pitching motion, a baseball pitcher exerted an average horizontal force of 80 N against the 0.15 kg baseball while moving it through a horizontal displacement of 2.2 m before he released it. How much work did the pitcher do to the baseball as a result of this force? If the baseball’s velocity at the start of the pitching action was zero, how fast was the ball moving at the instant of release?A car with mass 1520 kg is traveling down the highway at a speed of 18 m/s when the driver slams on the brakes due to an accident up ahead. The car eventually comes to rest.According to the work-energy theorem the work is related to the change in kinetic energy, Wnet = Δ KE = KEfinal - KEinitial.(a) Using the work-energy relationship, determine how much net work is done on the car from the brakes? Report the magnitude of the the work (positive value) even though the work from brakes will be negative since the car is slowing down._____ J(b) The brakes apply a force of 24000 N to the car in order to make it stop. Using the fact that W = F d and the fact that the you found the work done (magnitude) by the brakes in part (b), determine the stopping distance, d, of the car.____ m
- answer should be fractionState the condition when the work done by a force is (a) positive (b) negative. Explain with help of examples.In three cases, a force acts on a particle, and the particle is displaced from an initial position to a final position. The figure below shows the position-versus-force graphs, indicating the initial and final positions of the particle in each case. Find the work done by the force on the particle in each case.
