Question
Hey Guys, I got A and B. But I dont know how to get C A certain automobile manufacturer claims that its deluxe sports car will accelerate from rest to a speed of 40.5 m/s in 7.65 s. (a) Determine the average acceleration of the car. Correct: Your answer is correct. m/s2 (b) Assume that the car moves with constant acceleration. Find the distance the car travels in the first 7.65 s. Correct: Your answer is correct. m (c) What is the speed of the car 10.0 s after it begins its motion if it continues to move with the same acceleration? m/sExplanation / Answer
(a) By v = u + at
=>40.5 = 0 + a x 7.65
=>a = 5.294 m/s^2
(b) By s = ut + 1/2at^2
=>s = 0 + 1/2 x 5.294 x (7.65)^2
=>s = 151.9125 m
(c) BY v = u + at
=>v = 0 + 5.294 x 10.0
=>v = 52.94 m/s
