Question

An object accelerates from rest to 85 m/s over a distance of 36m . What acceleration did it experience ?

Answer 1

100m/s^2

Answer 2

using Vf=2a(deltaX)

Answer 3

this is only because it started from rest

Answer 4

Rest V1 = 0
V2 = 85 m/s
distance = 36m
acceleration = ?
best equation :
v2² = v1² + 2ad rearrange for acceleration and you get
A = v2² - v1² / 2d

Answer 5

Daboss 123 u forgot the ()
so A = (v2² - v1² )/ 2d

Answer 6

Thank you soooooo much !! 😄
