An object slides on a level floor. it slows and comes to a stop with a constant acceleration of magnitude 2.4 m/s2. what is the coefficient of kinetic friction between the object and the floor?

0.245

Explanation:

Force of the object = mass *acceleration of the body = 2.4m where m = mass,

And the Frictional force = force acting on the object due to its acceleration.

The force of normal due to the weight of the body = m*9.81.

Coefficient of kinetic friction = 2.4m/ 9.81m = 0.245.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

the force required to move the cart is divided by three or 33.33 n.
