During a very quick stop, a car decelerates at 7.05 m/s2. (a) what is the angular acceleration (in rad/s2) of its 0.270 m radius tires, assuming they do not slip on the pavement? (indicate the direction with the sign of your answer. assume the tires initially rotated in the positive direction.) -26.11 correct: your answer is correct. rad/s2 (b) how many revolutions do the tires make before coming to rest, given their initial angular velocity is 96.0 rad/s? 28 correct: your answer is correct. revolutions (c) how long (in s) does the car take to stop completely? 3.676 correct: your answer is correct. s (d) what distance (in m) does the car travel in this time? 95.11 incorrect: your answer is incorrect. m (e) what was the car's initial velocity (in m/s)? (indicate the direction with the sign of your answer.)

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 have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
