What is the rate of acceleration of 2000 kilogram truck if a force of 4200 n is used to make it start moving forward
sergij07 [2.7K]
<h3>Answer:</h3>

                 2.1 m.s⁻²

<h3>Solution:</h3>

Data Given:

                  Force  =  4200 N  =  4200 Kg.m.s⁻²

                  Mass  =  2000 Kg

                  Acceleration  =  ??

Formula Used;

                  Force  =  Mass × Acceleration

Solving for Acceleration,

                  Acceleration  =  Force ÷ Mass

Putting values,

                  Acceleration  =  4200 Kg.m.s⁻² ÷ 2000 Kg

                  Acceleration  = 2.1 m.s⁻²
