Answer #1

The constant force F moves the object along a straight line from the point (10, 3, 5) to the point (8, 9, 9).

The displacement vector is given by

The constant force is given by

Distance is measured in meters and Force is measured in newtons.

The work done by the constant force F is the dot product of F and D vector.

Hence, the work done W is

A sled with mass 15 kg moves in a straight line on a horizontal surface as it is being pulled by a force F at an angle of 30°with the direction of motion. A force of friction of 10 N acts on the sled. At one point in its path, its speed is 4.0 m/s; after it has traveled a distance 5.0 m beyond this point, its speed is 7.0 m/s. Use the work-energy theorem to find the total work...

A point moves along a straight line. It is uniformly accelerated from rest to 48 fps to the right in 2 sec. The acceleration is then changed to a different constant value such that the displacement for the entire period is 48 ft to the right and the total distance travelled is 192 ft. Determine (a) the total time interval (b) the final velocity.
