A 10 kg box accelerates for at a rate of 12 miles per second what is the force acting on the box
lions [1.4K]

193080N

Explanation:

Given parameters:

Mass of the box = 10kg

Acceleration = 12miles per second

Unknown:

Force on the box = ?

Solution:

The force acting on the box is function of the mass and acceleration of the box.

  Force = mass x acceleration

   Now we need to convert the given acceleration to m/s

     1000m = 1km

      1.609km = 1miles

    \frac{12 miles }{seconds } x \frac{1.609km}{1miles} x \frac{1000}{1km}

      = 19308m/s

 Force on box = 10 x 19308 = 193080N
