A force of 3,000 N is applied to a car, resulting in acceleration. In 10 s, the car increases its velocity from 0 m/s to 30 m/s. What is the mass of the car?​

Final answer:

The mass of the car is calculated using Newton's second law of motion, yielding a result of 1,000 kg.

Step-by-step explanation:

The mass of the car can be calculated using Newton's second law of motion, which states that force equals mass times acceleration (F = ma). We are given that a force of 3,000 N accelerates the car from 0 m/s to 30 m/s in 10 s. To find the acceleration, we use the formula acceleration (a) = change in velocity (Δv) / time (t). The change in velocity Δv is 30 m/s - 0 m/s = 30 m/s, and the time t is 10 s, so the acceleration a is 3 m/s2. Now applying Newton's second law, we have F = ma, where F is 3,000 N and a is 3 m/s2, we can solve for m (mass) as m = F / a = 3,000 N / 3 m/s2 = 1,000 kg. Therefore, the mass of the car is 1,000 kg.
