How To Find Kinetic Energy Crate Being Pushed Across Floor

A eq 100 mathrm lb eq crate is being pushed across a wooden floor with a force of eq 40 mathrm lb eq.

How to find kinetic energy crate being pushed across floor.

A 1 20 x 10 2 kg crate is being pushed across a horizontal floor by a force p that makes an angle of 30 0 degrees below the horizontal. Applied pushing force directed in the positive direction. If eq mu 0 3 eq find the acceleration of the crate. The horizontal forces acting on the crate are.

If acceleration of the crate g 10 m s2. Retarding friction force f k directed in the negative direction. We re asked to find the acceleration of a crate along a floor given the coefficient of kinetic friction the mass and the applied force. Using newton s equation f ma you will find the acceleration by dividing the net force by the mass of the crate the mass is 925 one standard gravity 9 80665 m s s or 94 32 kg.

The equation for the net horizontal force is thus. This is the component of force acting parallel to the floor take the difference between these two and you will have the net force pulling the crate which is 63 3 n.
