Prelecture Concept Question 7.06 Part A An object weighing 20 N moves horizontally toward the right a distance of 5.0 m. What is the work don O The work done on the object by the force of gravity is 100 J O The work done on the object by the force of gravity is 4.0 J. O The work done on the object by the force of gravity is 0.25 J O The work done on the object by the...
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.?
The force shown moves an object from x = 0 to x = 0.75 m. How much work is done by the force if the object moves from x = 0.05 m to x = 0.70 m ?
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.
1. A Constant force pushes an object and speeds it up. The object moves from (6i - 8j + 4k)m to (11i - 5j + 4k)m. The net force acting on the object is (2i + 4j + 5k)N. What is the increase in it's kinetic energy, in J? So I found in the x direction to be 10 J and in the y direction to be 12 J. I ignored the work in the k direction as the object...
For 3.0 seconds, Allison exerts a net force of 10.0 N on a 6.7 kg shopping cart that was initially at rest. Find the acceleration of the cart, and show that it moves a distance of 6.7 m.

Please show calculations :)
m / A ball moves subject to a force that varies with position. The force is F (7) = kxî. If k = 101 m, and the ball moves from ři = 11.5mi – 11.5mj to r2 = 7.2mi – 7.2mj, what is the work done by the force? Answer in Joules. Note that this is a conservative force, and that since there is no component of force in the y-direction, motion in the y-direction does...
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.
