Yes!

Since F = ma and we know a, we can re-write this as m = F/a. The info panel tells us that the inward or centripetal force needed is 2812.5 N and since a = 2.812 m/s², it follows that the mass of the car is:

m = 2812.5 N/ 2.812 m/s² = 1000 kg.

(Of course, you could also use the weight of the car as given and also deduce the mass as 1000 kg.)
