Question

An applied force of 50 N is used to accelerate an object, that weighs 73 N, to the right across a frictional surface. The object encounters 10 N of friction. What is the acceleration of the object?

Answer 1

Answer:

5.38 m/s^2

Explanation:

NET force causing the object to accelerate  =  50 -10 = 40 N

Mass of the object =  73 N / 9.81 m/s^2 = 7.44 kg

F = ma

40 = 7.44 * a         a = 5.38 m/s^2
