49) Make and Use Tables Three toy cars, each with a mass of 0.050 kg, roll down ramps with different heights. The height of each ramp and the speed of each car at the bottom of each ramp is given in the table. Copy and complete the table by calculating the GPE for each car at the top of the ramp relative to the bottom of the ramp and the KE at the bottom from each car’s motion down the ramp. Round your values two decimal places. How do the values of GPE and KE you calculate compare?

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?
