5. #264] Speeding car A car accelerates with a constant acceleration of 1.8 m s 2 along a long straight road. How long does it take the car to accelerate from 100 kph to 110 kph, and how far does it travel while doing so? [Hint: watch your units and sig figs! Because there is no other information, take the speeds as three significant figures] It takes seconds to accelerate to 110 kph. While accelerating, the car travels. m.
