(a) What is mass of the car?

Can you guys figure it out??

i got 2020.185 for K constant and then i used the formula m=kt^2/4pi^2 but that is wrong and it's giving me the same mass help or guide me please.

**drwls**, Tuesday, April 13, 2010 at 4:32pmFrom the compression deltaX of the springs when they get in, you know that the spring constant of the suspension system is

k = F/deltaX = 131*g*/0.093 = 13800 N/m

The oscillation period is 2 pi sqrt [(M+m)/k] = 1.6

where M is the car weight and m is the additional weight of the passengers.

Solve for M+m and them subtract m

(M+m)/k = 6.48*10^-2 s^2

M+m = 895 kg

m = 764 kg
