The velocity of a car increaaes from 43.2 km/h [n] to 86.4 km/h [n] over a 3 second interval. what is the cars acceleration in m/s?

Sol. Initial velocity u = 43.2 km/hr = 12 m/s u = 12 m/s, v = 0 a = –6 m/s2 (deceleration) Distance S = (V^2-u^2)/(2 (-6)) = 12 m

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

the assestment will probley apele with cause and effect
