A 4-N force is applied to a 2-kg object that is moving at 3 m/s. This
force is parallel to the object's velocity. After the object has travelled
an additional 5 m, the force is removed. The work done by this force
is:
А. 12)
В. 15J
C. 18J
D. 20J

A dog team exerts a horizontal force to a sledge weighing 5000 N
including load. It is pulled on level snow with a coefficient of kinetic
friction of 0.05. How much work is done by the dog team pulling the
sledge 1000 m at constant speed?
A. 2.5 X 104 J
В. 2.5 X 105 J
C. 2.5 X 106 J
D. 2.5 X 10' J

A man pushes an 80-N crate up a frictionless slope that makes an
angle of 30° with the horizontal. The man was able to push it to a
distance of 5.0m along the slope with a force parallel also to the
slope. However the speed of the crate decreases at a rate of 1.5 m/s?.
The work being done by the man is:
A. -200 J
В. 61 J
С. 140 J
D. 200 J](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb6c3684b-91a7-4765-8920-f169e7fe62fb%2F257f1df6-886d-413b-b9fc-d06e42c0a2f6%2Fiaeg11_processed.jpeg&w=3840&q=75)
