How much work is done by gravity on an object sliding down an inclined plane?

Click For Summary
SUMMARY

The work done by gravity on an object sliding down an inclined plane can be calculated using the formula W = mgh, where m is the mass, g is the acceleration due to gravity, and h is the change in height. In this scenario, a 10.0 kg object slides down a 2.00 m distance along a 30.0° incline. The vertical height (h) can be determined using trigonometric functions, resulting in a height of 1.00 m. Therefore, the work done by gravity is 10.0 kg * 10.0 m/s² * 1.00 m = 100.0 J.

An object of mass 10.0 kg is released from the top of an inclined plane which makes an angle of inclination of 30.0� with the horizontal. The object slides along the inclined plane. The questions refer to the instant when the object has traveled through a distance of 2.00 m measured along the slope. The coefficient of kinetic friction between the mass and the surface is 0.200. Use g = 10.0 m/s2. How much work is done by gravity?

Can anyone please help me out?
 
gravity is a conservative force which means that only the change in vertical height (not distance travelled) matters when measuring work done by gravity.
