An object starts moving with speed 20 m/s to the top of an inclined plane(inclined angle=30) due to an external for 250N.The mass of it is 25kg,the coefficient of kinetic friction is 0.15 and the length of the ramp is 25 m .Find the following 1. The work done by Friction Force ? 2.The object 's velocity when it reaches the top of this ramp

Answer rating: 100% (QA)

To solve this problem we need to break it down into two parts first finding the work done by the friction force and second determining the objects vel... View the full answer
