A car of mass 1000 kg moving with a speed `18 km h^(-1)` on a smooth road and colliding with a horizontally mounted spring of spring constant `6.25 xx10^3 N m^(-1)`. The maximum compression of the spring is

Text Solution

Verified by Experts

`1/2mv^(2)=1/2kx^(2)`
`:." "x=vsqrt(m//k)`
`v=18" km/h"=5" m/s"`
`:." "x=5xxsqrt((1000)/(6.25xx10^(3)))`
`x=2.0`m
