samuel has is observing an object. you please determine the work that is done by F = 5i -2j+0k which is a force that is constant in moving samuel's object in a plane . samuel tells you that the object moves due to the force in a straight line in the plane. the straight line connects the points A(1,2) and the point B(3,7). I already know that the correct answer to this question is zero. but the question I have is WHY is it zero. explain why the work is zero in this senario. Not how you get to the answer zero, but why the answer zero can make sense in this scenario. is the forece perpendicualr to the direction? i am confused please help and i will like.

In the plot shown of force vs. distance, approximately how much work is done in moving an object from x = 5 m to x = 15 m? Express your answers in Joules. F 30 N 20 N 10 N 5 m 10 m 15 m 20 m

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 worker pushes a wheelbarrow with a horizontal force of 50 N on level ground over a distance of 5.0 m. If a friction force of 43 N acts on the wheelbarrow in a direction opposite that of the worker, what work is done on the wheelbarrow by the worker? 250 J 215 J 35 J O 10 J O None of these answers is correct.

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?

A variable force (in Newtons) acting on an object is represented by the function F(x) = 4x3+ 3x2− 8 where x is the distance in meters from the origin. How much work is required to move an object from x = 1 to x = 5?

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?

Do the following situations result in positive work, negative work, or zero work? Force is perpendicular to displacement. A force slows an object down. Force acts in the same direction as displacement. Force acts in the opposite direction of displacement. A force acts on an object that remains stationary.

Consider an object of mass m = 4 kg on a frictionless table. The object experiences a repulsive force F = a/x2 + b/x, where F is in newtons and x is the position of the object relative to the origin. Write an expression for the work done by the repulsive force on the object as it moves from an initial position of x1 to a final position of x2.    If the object starts at a position of x1 = 8.5 m apart, how much work, in joules, is required by an external force to bring it to a position of x2 = 2.5 m apart when a = 19 and b = 11?    If the object starts at rest at a position x3 = 1.3 m and is released, at what speed v, in meters per second, will the object be moving when it is at position x4 = 12.5 m?

A 600 N person climbs a ladder at a constant speed. The person climbs up 12 meters in a time of 20 seconds. What is the work done and the power exerted?
