Ms. Rhea Carmon conducted an experiment with a radio-controlled toy car. The car startes 20 m/s and after 2.0 sec has reached a velocity of 30.0 m/s. What is the average acceleration of the car?
20 m/s/s
5 m/s/s
15 m/s/s
10 m/s/s

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?

You are doing a science experiment with a fahrenheit thermometer. your data must be in degrees celsius. if you measure a temperature of 125°f, what is this temperature in degrees celsius
