Ahorizontal force of 24 n is being applied to a box on a level surface. the box is accelerating at the rate of 2.0 against a frictional force of 14 n. what is the mass of the box?

Given:

The sum of horizontal forces will be:

→

hence,

The mass will be:

→

Thus the aforementioned answer is correct.

For SI units the mass m = 5 kg.

Explanation:

The sum of all horizontal forces is must be equal to maₓ:

∑Fₓ = maₓ = 24N - 14N = 10N

maₓ = 10N

m = 10N / aₓ = 10N / 2 m/s² = 5 m/s

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
