Answer:
x = 3.5 cm
Explanation:
When spring is used as a lift tool
so the mass suspended on it will have spring force on it
So as per the force equation of mass we can say

now net force on the mass is


here we have

now we have



Answer:
Given
acceleration (a) =1.5ms2
Force(F) =2100N
R. t. c mass (m) =?
Form
F=ma(divided by m both sides)
m=F/a
m=2100/105
m=1400kg
mass of car =1400kg
