A car engine exerts a force of 3285 Non a car which is accelerating at 2.56 m/s ^ 2 What is the mass of the car?

1283.20 kg

Explanation:

By Newton's Second Law, we know that F=ma.

a = 2.56m/s^2

F = 3285 N (1 N = 1kg*m/s^2)

F = ma -> m = F/a

m = (3285 N)/(2.56 m/s^2)

m = 1283.20 kg

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
