An object of mass 3.00 kg is subject to a force E, that varies with the position as in the figure below. (a) Find the work done by the force on the object as it moves from x = 0 to x = 5.00 m. (b) Find the work done by the force on the object as it moves from x = 5.00 m to x = 12.0 m. (c) Find the work done by the force on the object as it moves from x = 12.0 m to x = 17.0 m. (d) If the object has a speed of 0.400 m/s at x 0, find its speed at x = 5.00 m and its speed at x = 17.0 m. F, (N) 4 3 2 x (m) 4 8 10 12 14 16 18 20

A coin slides over a frictionless plane and across an xy coordinate system from the origin to a point with xy coordinates (3.70 m, 4.78 m) while a constant force acts on it. The force has magnitude 2.08 N and is directed at a counterclockwise angle of 100° from the positive direction of the x axis. How much work is done by the force on the coin during the displacement?

A person pulls a crate 43.5 meters along a horizontal floor by a constant force 112.3 N, which acts at 37.7 degrees. The floor is rough and exerts a friction force 49 N. What is the total net work done on the crate?

Bob is pulling a box of his toys of mass 15.0 kg along a rough horizontal surface for a distance of 6.00 m. The tension force in the rope is 58.0 N and the angle is 30° with respect to the horizontal. The frictional force on the box is 12.0 N.  How much work is done on the box by the normal force, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

You have two vectors: A = 7.27î + 3ĵ and B = 4î - 0.95ĵ + 12k. If vector A represents a force vector and vector B is a displacement vector, what is the magnitude of work done by this force?

Two forces F1 = (-1.5i-0.8j+0.7k) N and F2 = (-0.7i+1.2j) N, are applied to a moving object. what is the net force on the object? if the displacement vectoris d= (8.0i+6.0j+5.0k) m, what is the work done by these two forces?

A block of mass m = 3.1 kg is placed on a rough incline surface making an angle e = 13.5. with horizontal. A force F parallel to the ground is applied to the block. Due to the applied force the block moved x = 1.2 meter along the inclined surface with constant speed. If the inclined surface has kinetic friction coefficient Hk = 0.29 what is the work done by the applied force? Provide your answer with 2 decimal places. Take g = 9.81 m/s2 F m

A bicyclist starting from rest applies a force of F = 239 N to ride his bicycle across flat ground for a distance of d = 210 m before encountering a hill making an angle of θ = 17 degrees with respect to the horizontal. The bicycle and rider have a mass of m = 120 kg combined. In this problem, you can ignore air resistance and other losses due to friction.How much work, W in joules, did the rider do before reaching the hill? What is the bicycle's speed, v in m/s, just before the hill? If the cyclist starts coasting at the bottom of the hill, what distance, di in meters, does the bike travel up the incline?

a) A stationary bowler is getting ready to throw the bowling ball. She holds a 6.0 kg bowling ball 1.4 m above the ground for 2.0 s. How much work is done on the ball by the bowler? b) A pencil case is pushed eastward with a force of 11 N. Over what distance did the force act on the pencil case if it did 14 J of work on it?
