A 6 kg block slides on a horizontal frictionless surface with a speed of 1.5 m/s . It is brought momentarily to rest when it hits a bumper that compresses a spring. The acceleration of gravity is 9.8 m/s2 .How much is the spring compressed if its
force constant is 7 kN/m?

1/2 mv^2= 1/2 kx^2
X=1.3887 WRONG

• Physics * (Wht am I doing wrng? answ provided) -

K=7kN/m = 7000N/m

Otherwise,ok.
