Aspeed trap is set up with two pressure-activated
stripsplaced across a highway, 110 m apart. a car is speeding
alongat 33m/s, while the speed limit is 21 m/s. at the instant
thecar activates the first strip, the driver begins slowingdown.
what minimum deceleration is needed in order that theaverage speed
is within the limit by the time the car crosses thesecond
marker?
