Use g = 10 m/s/s. You push a 30 kg stationary box across a rough surface with a sideway force of 80 N in the positive direction over a time of 4 seconds. The coefficient of kinetic friction is 0.20. Let the direction to the right be positive. Required:
a. What is the contribution from the push force to the total impulse?
b. What is the contribution from the friction force to the total impulse?
c. What is the total impulse given to the box?
d. What is the final velocity of the box?

Good Luck!

Explanation:

there are no correct statementd on the list of choices you provided.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
