Answer:

Pressure

Explanation:

                                  V α T

                                  V = kT

What is the rate of acceleration of a 2,000-kilogram truck if a force of 4,200n is used to make it start moving forward?
butalik [34]

Answer:

The answer to your question is:      a = 2.1 m/s²

Explanation:

Data

Acceleration : ?

Mass = 2000 kg

Force = 4200 N

Formula

Newton's second law of motion    F = ma

                                                        a = F / m

Substitution

                                     a = 4200 N / 2000 kg

                                      a = 2.1 m/s²
