Question

A box of mass 30 kg is pushed horizontally across the floor with a force to the left of 210 N and to the right with a force of 50 N. The coefficient of friction is 0.2. Determine, a) the weight of the box.

Answer 1

The weight of the box is 294 N.

Step-by-step explanation:

To determine the weight of the box, we need to use the formula Weight = mass x acceleration due to gravity.

Since the box is not accelerating vertically, the weight of the box is equal to the normal force acting on it.

The normal force is calculated by multiplying the mass of the box by the acceleration due to gravity (9.8 m/s²).

Weight = 30 kg x 9.8 m/s² = 294 N
