sue drives her 1452 kg car along a straight road at a constant velocity of 30 m/s [E]. Ger brakes suddently give out. she puts the car in neutral and lets it coast for 25 seconds. The air drag decelerates the car to a velocityof 25 m/s [E]. assume a frictionless surface. PART C IS WHERE IM CONFUSED, BUT YOU'LL NEED TO KNOW MY ANSWERS TO THE OTHER ONES FIRST. b)determine average acceleration while car's decelerating m=1452 kh v1=30 m/s [E] v2=25 m/s [E] t=25s d=1/2(v1+v2)(t) =1/2(55)(25) =688 m a= v2squared-v1squared/2(d) =25squared-30squared/2(688) = -0.20 m/ssquared b)determine average force of air against car F=(m)(a) =(1452)(-.2) =-290.4N c)after coasting for 25s, she pulls her e-brake to slow to the car to a stop. If it takes 3s to stop the car, what is the force applied by the e-brake? Assume that the force exerted by the air remains constant and is equal to the forst determined in part (b).
