Obtain the equations of motion for each mass. inthe mechanical system shown in figure p2 6, the spring forces are zero when x2+小ouet the base be stationary so that x3( 0 for ail values of t draw free-body dagams and write a pair of coupled differential equations that govern the motion when the only inout is fat figure p26 a, m, b,

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?
