Knowing that it becomes airborne 30 s laterat B and that the distance AB is 900 m, determine (a) the acceleration a(b) the take-off velocity VB.A00000Fig. P11.34OO00000000Fig. P11.3311.34 A motorist is traveling at 54 km/h when she observes that a trafficlight 240 m ahead of her turns red. The traffic light is timed to stayred for 24 s. If the motorist wishes to pass the light without stoppingjust as it turns green again, determine (a) the required uniform decel-eration of the car, (b) the speed of the car as it passes the light.54 km/h240 m11.35 Steep safety ramps are built beside mountain highways to enablevehicles with defective brakes to stop safely. A truck enters a 750-ftramp at a high speed vo and travels 540 ft in 6 s at constant decelera-tion before its speed is reduced to vo/2. Assuming the same constantdeceleration, determine (a) the additional time required for the truckto stop (b) the additional distance traveled by the truck.0
