A 2 kg block slides on a rough horizontal surface with muk=0.6. It has an initial velocity of 5 m/s. Use g = 10 m/s2 The initial kinetic eneryg of the block is : J.

As the block slides a distance of 0.8 m, the work done by friction is: J. (be careful)

The final kinetic energy of the block after sliding 0.8 m is: J.

The final speed of the block after sliding 0.8 m is: J. (Use 2 significant figures)
