Force is defined as the product of mass of the body and its acceleration.

In the question we are given,

Force (F) = 5050 N

Acceleration (a) = 9.71 m/[tex]s^{2}[/tex]

Now, According to Newton's second law of motion ,

F= m*a

Dividing both sides by a, we get

[tex]\frac{F}{a}[/tex]=m

or,

m=[tex]\frac{F}{a}[/tex]

Putting the values of F and a we get,

m= [tex]\frac{5050}{9.71}[/tex]

m=520.08 kg

Hence, the mass of Munster's Car ≈ 520 kg.
