S 17 g My sister Sara is pulling a box along a horizontal surface with the force F inclined at an angle 0 with the horizontal. The box moves a distance d. F 1 say that the work done by the force of gravity is equal to zero. O True O False OL MA

Suppose a particle moves from point a to point b, along path 1. If only non conservative force acts on the particle, then any choice of path between a and b gives the same amount of work. True or False? а. True b. False

Soru 5 F. N An object of mass m=1kg moving along the x-axis passes through the point x = 0 with a speed of 2 m/s. The force, applied along the x-axis, varies with position as shown in the 5. figure. 3 a) Calculate the kinetic energy of the object when it passes through x= 0. b) Calculate the work done by the F, force while moving from 3 I, m x = 0 to x= 4m. c) Calculate the velocity of the object at x = 4m.

A car is parked on a hill. The gravitational force on the car is 9.31 x 103 N straight downward, and the angle of the hill is 4° from the horizontal. The car’s brakes fail, and the car slides 30.0 m downhill. a) Calculate the component of the gravitational force that acts parallel to the car’s motion.  b) Calculate the work done on the car by gravity as the car slides.

A block of weight w = 25.0 N sits on a frictionless inclined plane, which makes an angle θ = 30.0 ∘ with respect to the horizontal, as shown in the figure. A force of magnitude F = 12.5 N applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. Part A The block moves up an incline with constant speed. What is the total work Wtotal done on the block by all forces as the block moves a distance L = 2.70 m up the incline? Include only the work done after the block has started moving at constant speed, not the work needed to start the block moving from rest. Part B What is Wg, the work done on the block by the force of gravity w⃗  as the block moves a distance L = 2.70 m up the incline? Part C What is WF, the work done on the block by the applied force F⃗  as the block moves a distance L = 2.70 m up the incline?   Part D What is WN, the work done on the block by the normal force as the block moves a distance L = 2.70 m up the inclined plane?
