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?
Answer in units of m.
My answers are incorrect please help!
1/2 mv^2= 1/2 kx^2
1ST ANSWER (1/2)(6)(1.5^2)=(1/2)(7)X^2
X=1.3887 WRONG
2ND ANSWER (1/2)(6)(1.5^2)=(1/2)(.007)X^2 X=43.9155 WRONG
