The highest involuntary deceleration survived by a human is 1762 m/s2. Formula-1 racecar driver David Purley crashed into a wall going 110 mph. How much distance in meters was covered during this massive deceleration? Report answer with two significant digits and do not forget units.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
