A 6.2 kg block is pushed across a horizontal surface
with a horizontal force of 50.9 N against a friction
force of 13.7 N. What is the acceleration of the
block? Please report your answer with 1 number
behind the decimal and select the correct unit.

Choose... -

6 m/s²

Explanation:

We are given;

We are required to determine the acceleration of the block.

Therefore;

F = Ma , where F is the resultant force, m is the mass and a is the acceleration.

In this case;

Resultant force, F = Horizontal force - friction force

                             = 50.9 N - 13.7 N

                             = 37.2 N

Thus;

37.2 N = 6.2 kg × a

Hence;

acceleration, a = 37.2 N ÷ 6.2 kg

                         = 6 m/s²

Therefore, the acceleration of the block is 6 m/s²

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.
