A 2.0-kg block sliding on a frictionless horizontal surface is attached to one end of a horizontal spring (k = 600 N/m) which has its other end fixed. The speed of the block when the spring is extended 20 cm is equal to 3.0 m/s. What is the maximum speed of this block as it oscillates?
a. 4.6 m/s
b. 5.3 m/s
c. 5.7 m/s
d. 4.9 m/s
e. 3.5 m/s
Question 2
The force an ideal spring exerts on an object is given by Fx = -kx, where x measures the displacement of the object from its equilibrium (x = 0) position. If k = 60 N/m, how much work is done by this force as the object moves from x = -0.20 m to x = 0?
a. -1.2 J
b. +1.2 J
c. +2.4 J
d. -2.4 J
e. +3.6 J
