A car is moving at a constant speed. If the force generated by the car to push it forward is 8,000 N, what can be said about the force opposing the car’s motion?

1.It is less than 8,000 N and greater than zero.
2.It is exactly 8,000 N.
3.It is greater than 8,000 N.
4.It is zero.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
