Perform the calculation you set up in part A. Express your answer to the correct number of significant figures. Type the correct answer in the box.
The car will travel
meters using 52,700 joules joules of energy.

- the answer is 2900, I just took the test and others were saying 2,858 but I got that wrong and it says it’s 2900

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
