A0.37 kg object is attached to a spring with a spring constant 175 n/m so that the object is allowed to move on a horizontal frictionless surface. the object is released from rest when the spring is compressed 0.19 m. find the force on the object when it is released. answer in units of n. what is the acceleration at this instant? answer in units of m/s^2.

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
