A 10.0 kg block on a smooth horizontal surface is acted upon by two forces: a horizontal force of 30 N acting to the right and a horizontal force of 60N to the left. What acceleration will the block experience?

Explanation:

Second Newton's Law

It allows to compute the acceleration of an object of mass m subject to a net force Fn. The relation is given by

The net force is the sum of all vector forces applied to the object. The block has two horizontal forces applied (in absence of friction): The 30 N force acting to the right and the 60 N force to the left. The positive horizontal direction is assumed to the right, so the net force is

Thus, the acceleration can be computed by

The negative sign indicates the block is accelerated to the left

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
