A car start from rest and attain a velocity of 20 m/s in 5 s. Calculate the distance during the time |
|
Answer» car traveled 50 m while ACCELERATING from 0 to 20 m/s in 5 seconds. The distance d is from d = v(avg) • t where v(avg) is the average velocity during the TIME, or v(avg) = v(INITIAL) + ∆v/2. Here v(initial) is 0 and ∆v is 20 m/s, so v(avg) = 20 m/s / 2 = 10 m/s. d = 10 m/s • 5 s = 50 m. |
