If the mass of a box is 200 Kg, with what net force would you use to make the box accelerate 2.4 m/s 2 ?

The net force used on the box was 480 N

Explanation:

Mechanical Force

According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:

F = ma

Where a is the acceleration of the object.

The mass of a box is m=200 kg and it's accelerated at a=2.4\ m/s^2 by a net force whose magnitude is:

F = 200 * 2.4 N

F = 480 N

The net force used on the box was 480 N

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
