A 48-kg block is pushed across a horizontal surface with a horizontal force of 98 N against a friction force of 12 N. The acceleration of the block is
netforce=mass*a
98-12=48*a
solve for acceleration a
38
To find the acceleration of the block, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.
The net force acting on the block can be calculated by subtracting the friction force from the applied force:
Net force = Applied force - Friction force
= 98 N - 12 N
= 86 N
Now we can calculate the acceleration using Newton's second law:
Acceleration = Net force / Mass
= 86 N / 48 kg
= 1.79 m/s²
Therefore, the acceleration of the block is 1.79 m/s².
To find the acceleration of the block, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
The force acting on the block is the difference between the applied force and the friction force:
Net force = Applied force - Friction force
Net force = 98 N - 12 N
Net force = 86 N
Now, we can use Newton's second law:
Net force = Mass x Acceleration
86 N = 48 kg x Acceleration
To find the acceleration, we rearrange the equation:
Acceleration = Net force / Mass
Acceleration = 86 N / 48 kg
Calculating the acceleration:
Acceleration = 1.792 m/s^2
Therefore, the acceleration of the block is 1.792 m/s^2.
