Abox with a mass of 100.0 kg slides down a ramp with a 50 degree angle. what is the weight of the box? n what is the value of the normal force? round the answer to the nearest whole number. n what is the acceleration of the box? (disregard friction and air resistance.) round the answer to the nearest tenth.

1) weight of the box: 980 N

The weight of the box is given by:

where m=100.0 kg is the mass of the box, and is the acceleration due to gravity. Substituting in the formula, we find

2) Normal force: 630 N

The magnitude of the normal force is equal to the component of the weight which is perpendicular to the ramp, which is given by

where W is the weight of the box, calculated in the previous step, and is the angle of the ramp. Substituting, we find

3) Acceleration:

The acceleration of the box along the ramp is equal to the component of the acceleration of gravity parallel to the ramp, which is given by

Substituting, we find
