- You attach a 2.10 kg weight to a horizontal spring that is fixed at one end. You pull the weight until the spring is stretched by 0.300 m and release it from rest. Assume the weight slides on a horizontal surface with negligible friction. The weight reaches a speed 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)? 18.85 x Your answer is off by a factor of 2.
