Answer :
The acceleration of the block is 7.8 m/s².
What do you mean by acceleration?
The rate at which an object's velocity with respect to time changes is referred to as acceleration. It is a vector quantity to accelerate (in that they have magnitude and direction).
To find the acceleration of the block, we can use the equation:
force = mass X acceleration + friction
Rearranging the equation, we can find the acceleration:
acceleration = (force - friction) / mass
The force of friction can be found using the equation:
friction = friction coefficient X normal force
The normal force is equal to the weight of the object, which can be found using the equation:
weight = mass X gravity
So, friction = friction coefficient X mass X gravity
We know that gravity is 9.8 m/s²
friction = .15 * 14 kg * 9.8 m/s²
Now we can substitute this value for friction and the known values for force and mass into the first equation and solve for acceleration:
acceleration = (112 N - 1.47 N) / 14 kg
acceleration = 7.8 m/s²
So, the acceleration of the block is 7.8 m/s².
