A10 kg block is pushed with a constant horizontal force of 20 n against a constant horizontal frictional force of 10 n. what is the acceleration of the block?

The acceleration would be a=1 m/s^2. Let's explain why.

Explanation:

Let's say the block is □

20N→□    Block is pushed with a constant horizontal force of 20N

□←10N     It is known that frictional force is the opposite way of the movement

So it is safe to say that there is 10 N force trying to stop the block.

In this case our net force is

According to Newton's second motion law

(m=mass, F=force, a=acceleration

→

As an extra information the block also applies gravitational m.g force down but since there is no other force applies in the vertical way, ground compansate the force.

your answer would be fusion

the assestment will probley apele with cause and effect
