Question

The weight of a car produces a downward force of 10,000 N. This pushes each of the four spring in its suspension down by 20 cm. If five adults get into the car, the downward force increases by 4000 N. If the force is shared equally by the four springs, how much more will they be pushed down ?

Answer 1

Answer:

14 cm

Explanation:

F=Kx

10000=k×20. ...(i)

14000=k×x'. ....(ii)

Division of ..(ii) by ..(i)

14/10=x'/20

X'=28cm

So further push =14 cm
