Dwight uses a spring (k = 70 n/m) on a horizontal surface to make a launcher for model cars. the spring is attached to a holder that has a mass of 0.3 kg. if he compresses the spring and releases it, the launcher will move back and forth in periodic motion.
a. if he compresses the spring by 0.4 m and releases it, what is the acceleration of the launcher as the spring reaches its natural length?
b. what is the maximum kinetic energy fo the launcher?
c. what is the maximum speed of the launcher?
