A 2 kg block is pushed on sandpaper with a force of 10 N. The friction from the sandpaper is 2 N.
Which of the below will you use to calculate the net force on the block?
To calculate the net force on the block, you would subtract the force of friction from the applied force. Therefore, you would use the equation:
Net force = Applied force - Force of friction
In this case, the applied force is 10 N and the force of friction is 2 N, so:
Net force = 10 N - 2 N = 8 N
To calculate the net force on the block, you can use the equation:
Net force = Applied force - Frictional force
In this case, the applied force is 10 N and the frictional force is 2 N. So, using the equation, the net force on the block would be:
Net force = 10 N - 2 N = 8 N
To calculate the net force on the block, you need to 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.
Net force (Fnet) = mass (m) × acceleration (a)
In this case, the mass of the block is given as 2 kg, and the force applied to the block is 10 N. However, we also need to consider the friction force acting on the block, which is 2 N.
Since friction acts in the opposite direction to the applied force, it will reduce the net force and hence the acceleration of the block. To calculate the net force, we need to subtract the friction force from the applied force.
Fnet = Fapplied - Friction
Fapplied = 10 N (given)
Friction = 2 N (given)
Therefore, the net force on the block can be calculated as:
Fnet = 10 N - 2 N
Fnet = 8 N
Hence, the net force on the block is 8 N.
