Multiple-Concept Example 6 presents a model for solving this problem. As far as vertical oscillations are concerned, a certain automobile can be considered to be mounted on four identical springs, each having a spring constant of 1.21 x 105 N/m. Then, four identical passengers are seated in the car, and it is set into a vertical oscillation that has a period of 0.371 s. If the mass of the empty car is 1400 kg, determine the mass of each passenger. Assume that the mass of the car and its passengers is distributed evenly over the springs.

Explanation:

Mass of car = 1400 kg

T = Time period = 0.371 s

k = Spring constant =

Time period is given by

The 4 in the numerator is because there are 4 springs

Mass of car with people is 1687.46 kg.

Mass of people

Mass of each person

Mass of each person is .

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
