The coefficient of kinetic friction between a box and the floor is 0.30. A person pushes horizontally on the box with a force of 185 N for a distance of 5.4 m. If the mass of the box is 45 kgwhat is the total work done on the box? (pls this quiz was due two days ago)

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Letter a, because when there are unlike charges they will always attract to each other.
