You are riding an elevator that is accelerating upward at 2.20 m/s².You have a spring balance accurately calibrated in newtons.When you hang a mass of 10.0 kg on the balance,the reading of the balance is A)120 N B)981 N C)76.0 N D)10.0 N E)9.81 N

Question

Quizplus · Accepted Answer

The force measured by the spring balance (apparent weight) can be calculated using the formula F = m(a + g), where m is the mass (10.0 kg), a is the acceleration of the elevator (2.20 m/s^2), and g is the acceleration due to gravity (9.81 m/s^2). Thus, F = 10.0 kg * (2.20 m/s^2 + 9.81 m/s^2) = 10.0 kg * 12.01 m/s^2 = 120.1 N, which is approximately 120 N.
