Question

The applied force is no longer applied, and the block is still on the new surface with a force of friction 20N. We now observe the block when it is moving with a velocity of 40m/s.

a) How long will it take the block to slow down?

b) How far will the block travel before it slows down to a complete rest?

c) What is the magnitude of the net force on the block when it is finally at rest?

Acceleration = 10. m/s?

The applied force is no longer being applied, and the block is still on the new surface with a force of friction of 20 N. We now observe the block when it is moving with a velocity of 40 m/s.
How long will it take the block slow down to a complete rest?
