Question

In a performance test, each of two cars takes 9.0 s to accelerate from rest to 27 m/s. Car A has a mass of 1409 kg, and car B has a mass of 1917 kg. Find the net average force that acts on (a) car A and (b) car B during the test.

Step 1

Given: Mass of car A, \(m_A = 1409 \, \text{kg}\) Final velocity of car A, \(v_A = 27 \, \text{m/s}\) Time taken for acceleration, \(t = 9.0 \, \text{s}\) Using the formula \(F = \frac{m \cdot (v_f - v_i)}{t}\), where \(m\) is the mass of the car, \(v_f\) is the Show more…
