You attach a 2.50 kg weight to a horizontal spring that is fixed at one end. You pull the weight until the spring is stretched by0.400 m and release it from rest. Assume the weight slides on a horizontal surface with negligible friction. The weight reaches aspeed of zero again 0.100 s after release (for the first time after release). What is the maximum speed of the weight (in m/s)?25.12Your answer is off by a factor of 2. Note that the given time is the amount of time to make one half of a period, not a full period.m/s
