Acompact car has a mass of 1300 kg . when empty, the car bounces up and down on its springs 1.5 times per second. what is the car's oscillation frequency while carrying four 78 kg passengers?

0.76 oscillations per second

Explanation:

Time period = where k is the spring constant and m is the mass attached to the spring.

Calculating the spring constant:

1/1.5=;

k=3.68*10^4

When the car is loaded, its mass increases to 1300+ 4*78 = 1612

Calculating the new time period:

T==1.1315s

Frequency=1/T;
