Steven carefully places a m = 1.85 kg wooden block on a frictionless ramp so that the block begins to slide down the ramp from rest. The ramp makes an angle of θ = 51.3 ° up from the horizontal. Which forces do nonzero work on the block as it slides down the ramp?

Gravity force

Explanation:

We are given that

Mass of wooden block,m=1.85 kg

We have to find the force which do non zero work on the block as it slides down the ramp.

When a block slides down the ramp on a frictionless surface .

Then, weight act on the wooden block in downward direction.

We know that weight is that force which act on the body due to gravity.

Then, we can say that the force which do nonzero work on the block as it slides down the ramp is gravity force.

find the surface area of the sphere to the nearest square unit. use a calculator.
