Question
A mass m = 6.0 kg slides along a frictionless table with initial speed v as shown in the figure. It
strikes a coiled spring that has a force constant k = 350. N/m.
The mass compresses the spring a distance x2 - x1 = -10.0 cm before the mass comes to rest
momentarily.
x2 =
-5 cm x1
(A) Determine the initial speed v of the block before it comes into contact with the spring.
(B) Determine the work done by the spring on the block as it slows the block down from its initial
speed v to rest.
