Acar is traveling at 50 ft/s when the driver notices a stop sign 100 ft ahead and steps on the brake. assuming that the deceleration due to braking is constant, what is the magnitude of the minimum deceleration for which the car would stop right at the stop sign?

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
