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.
