Question

You attach a cart with a mass of 0.92 kg to a spring and compress the cart-

Answer 1

Answer:

F = - K X     force exerted by compressed spring

F X = 1/2 M V^2    energy (work) required to produce a speed V for mass M

K X * X  = 1/2 M V^2      direction of F is the same as that of V

X^2 = M V^2 / K      combining  terms

X = (M / K)^1/2 V      

X = (.92 / 130)^1/2 * 1.4 = .118 m
