Question

To determine the mass of a car, a student (with a friend at the wheel) pushes the car holding a bathroom scale between himself and the car. The scale maintains a constant reading of 532 N while the car accelerates on level ground. At the conclusion of the experiement, his friend reports that the car accelerated from rest to 13.9 km/hr in 17.0 s. What was the mass of the car?

Answer 1

\[F=ma\]\[m=F/a\]\[a=(v-u)/t\]\[m=Ft/(v-u)\]\[v=13.9 \times 1000/ 3600 \approx 3.86\]\[532 \times 17 / 3.86 \approx 2342kg\]

Answer 2

yo computer is not accepting the answer, is saying use fewer digit

Answer 3

would it like it in hexadecimal or something? (FYI 2342dec in hex =926)

Answer 4

that's 2.34 Mg

Answer 5

yeah correct!!!!
