Problem 3: A force F = 4x2 - 3x acts on an object as it moves along the x-axis. a) How much work is done by the force as the object moves from x = 2.0 m to x = 7.0 m? b) If the mass of the object is 5.0 kg and it started at rest, what is it's speed at x = 7.0 m? Please show step-by-step.
A force moves an object in the direction of the force. The graph shows the force versus the object's position (a) Find the work done when the object moves from 0 to 2.0 m. (b) If the mass of this object is 1.5 Kg and it started from rest find the final velocity at 2.0 m.
The force an ideal spring exerts on an object is given by Es=-la, where x measures the displacement of the object from its equilibrium (x = 0) position. If k= 60 Nm, how much work done by its force as the object moves from x = 0 m to x = -0.2 m? Select one: a. 2.4 J b. - 1.2 J C. 1.2 J d. Zero
A force acting on an object moving along the x axis is given by Fx = (14x - 3.0x2) N where x is in m. How much work is done by this force as the object moves from x = -1 m to x = +2 m? +12J +42J +32J +28J -12J
An object which is originally at location 〈 -2,0,0 〉m moves to a location 〈 -5,0,0 〉m as shown in the diagram above. While it is moving it is acted on by a constant force of 〈 -23,0,0 〉N. How much work is done on the object by this force? W= As a result, the kinetic energy of the object: Stays the same. Increases. Decreases.

Find the total work done by the force shown in Fig. 7-28, as the object on which it acts moves from x = 0 to x = 5.0 m.
The force field F (x, y) = (x + 4y)i + (x^2 − 3)j acts on an object traveling from (0, 0) to (0, 1). The object moves along the path x = c(y − y^2 ) with 0 ≤ y ≤ 1. Determine the value of c that minimizes the work done on the object by the force field. Please use the line work integral, and optimization
A force F = (3xi - 2xyj) N acts on an object as the object moves in the .x direction origin to .v 5.00 m (no motion in v-axis). The object has a mass m = 5.00 kg. Find the work done on the object by the force F. lf the object starts from rest, what is the final speed of the object at x = 5.00 m.?
An object of mass m = 4.2 kg moves under the influence of one force. That force causes the object to move along a path given by x = 6.8 + 5.2 t + 2.8 t2, where x is in meters and t is in seconds. Calculate the work done by the force on the object from t = 2.5 s to t = 6.5 s. ____J
