Question

a box with a mass of 50kg was accelerated with a force of 600n from rest. the force of friction was 100n what was the velocity after 10 seconds

Answer 1

Step-by-step explanation:

The net force accelerating the box is 600 -100 = 500 N

Remember:

F = ma

500 N = 50 kg * a shows a = 10 m/s^2

Now:

vf = a t

= 10 m/s^2 * 10 s = 100 m/s final speed
