An object started moving with an initial velocity of 10m/s after travelling a distance of 5m gets a velocity of 20m/s find its: (a)acceleration
(b)time taken
​

Respuesta :

Answer: a = 30 m/s^2

t = .33 s

Explanation:

(v final)^2 = (v initial)^2 + 2*a*d → 20^2 = 10^2 + (2)(a)(5) → a = 30 m/s^2

Acceleration = change in velocity / time → 30 = (20 - 10) / t → t = .33 s :)
