Question

A 10 kg mass rests on a table. What acceleration will be generated when a force of 20 N is applied and encounters a frictional force of 15 N?

A) 0.5 m/s^2
B) 3.5 m/s^2
C) 5 m/s^2
D) 35 m/s^2

Answer 1

The answer is A) because knowing Net force is equal too mass * acceleration, we can sub in what is given, the net force here would be 5N so the equation the looks like 5N=10kg*a and then dividing out 10kg we are then left with .5 m/s^2
