Answer:

3331.5 kg

Explanation:

given

spring constant of the spring(k)=24200N/m

frequency of oscillation (f)=0.429 hz

let the mass be m kg

now we know that a spring  mass system undergoes simple hormonic motion the frequency of the oscillation of SHM is given as

f=1/2 π√ k/m

rewrite the above equation interms of m this gives

2πf=√k/m

squaring both side we get

(2πf)²=k/m

m=k/4π²f²

now putting the given values

m = 24200/4*(3.14)²(0.429)²

m=3331.5

therefore the mass of the truck is 3331.5kg
