Mason lifts a box off the ground and places it in a car that is 0.50 meters high. if he applies a force of 8.0 newtons to lift this suitcase, what is the work done? a. 0 joules b. 4.0 joules c. 4.0 × 101 joules d. 4.0 × 102 joules

The work done to lift the suitcase is 4 Joule.

Option B is correct.

Given:

Height = 0.5 m

Force = 8 N

To find:

Work done = ?

Formula used:

Work done is given by,

W = f × s

where f = force

s = displacement

Solution:

Work done is given by,

W = f × s

where f = force

s = displacement = height

W = 8 × 0.5

W = 4 Joule

Thus the work done to lift the suitcase is 4 Joule.

Option B is correct.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
