Question

a plate of cafeteria food is on a horizontal table. you push it away from you with a constant horizontal force of 14.0 n . the plate has a mass of 0.680 kg , and during the push it has an acceleration of 12.0 m/s2 in the direction you are pushing it. what is the magnitude of the net external force on the plate during the push?

Answer 1

8.16 N

Step-by-step explanation:

Use Newton's 2nd Law (F = ma) to solve this:

Fnet = ma = (0.680 kg)(12 m/s²) = 8.16 N

Fnet < Fapplied due to friction
