Question

what is the acceleration of a 2,000- kilogram truck if a force of 4,200. N is used to make it start moving forward?

Answer 1

Newton's 2nd law of motion:              Force = (mass) x (acceleration)

Divide each side by (mass) :              Acceleration = (force) / (mass)

       Acceleration of the truck = (4,200 N) / (2,000 kg) = 2.1 m/s²
