a 2.0 kg block is projected down a plane that makes an angle of 20 degrees with an initial kinetic energy of 1.20 J. if the coefficient of kinetic friction between the block and the plane is 0.40, how will the block slide down along the plane before coming to rest?

Alright Dude, If that worked for you... don't forget to give THUMBS
UP.(that will work for me!)
Please Vote...
If I missed something feel free to leave a comment.
atleast before giving down vote.
and, Thanks for using homeworklib- Smarter way to study.

A block of mass 2.0 Kg is sliding down an inclined plane, as shown (the angle is 30 degrees). If the coefficient of kinetic friction is 0.250, determine the net acceleration of the block down the plane.
A 4.5-kg block slides down an inclined plane that makes an angle of 28° with the horizontal. Starting from rest, the block slides a distance of 2.4 m in 5.2 s. Find the coefficient of kinetic friction between the block and plane.
A 1 kg block slides down an inclined plane which makes an angle of 30degree to the horizontal. Starting from rest, it is found to have a speed of 3 m/s after it has moved through a distance of 1.6 m. Find the amount of mechanical energy dissipated due to friction as the block slides down the plane, and hence find the coefficient of friction between the block and the plane, Explain your steps and reasoning. Remember to draw a...
A block of wood of mass m = 1kg is pushed with an initial velocity of 1m/s down a ramp that makes an angle of 30 degrees with the horizontal. The coefficient of kinetic friction is 0.6. How far along the ramp does it slide before coming to rest?
9) A 2.00 kg box is launched up an inclined plane of angle 30 degrees with respect to the horizontal. The length of the inclined plane is 14.0 m. The coefficient of kinetic friction between the block and the inclined plane is u= 0.40. With what speed should the block be launched so that it just makes the top of the inclined plane? Work this problem using conservation of Energy. Hint: Conservation of Energy says that Wne+ ME, = ME,...
