a car starts from rest at a point 300m from a truch that is moving at a constant rate of 30m/s toward the car. IF the car accelerates at .8m/s2, determine the time it take for the car and the truck to meet. s=300 This is what I did Car: Vi = 0, a = .8 Vf^2=2as = Vf=21.9 Vf=at 21.9/.8 = 27.38 t=27.38sec Truck: S=(V/2)t S=(15)t 300/15 = 20 t=20 They meet after (27.38 -20) = 7.38 seconds. The answer given is 8.94seconds. Not sure what I am doing wrong?????
