7. A person pushes on a 5.00 kg box with a force of 15.0 N to the right. As a result, the box moves at a constant speed of 10.0 m/s.

Answer

Given,

Mass of the box, m = 5 kg

Force, F = 15 N

Speed of the box, v = 10 m/s

Assuming we need to determine weight, normal force, and the frictional force on the box.

Weight of the box = m g = 5 x 9.8 = 49 N

Normal force on the box =  Weight of the box = 49 N.

Frictional force on the box will be equal to 15 N because box is moving with constant velocity.

the body's situation won't change the forces are equal opposit and on the same body

technology is the application of the knowledge gained by science.
