Question

A Vehicle starts from rest and reaches a speed of 6 m/s in 3s. What is its acceleration?
​

Answer 1

Answer: We know that a = (v-u)/t where a is acceleration, v is the final velocity, u is the initial velocity and t is time.

v = 6m/s

u = 0m/s (as the body starts from rest)

t = 3s

a = ?

Substituting for the equation I already typed above, we have a = (6-0)/3 = 6/3 = 2

Therefore, the acceleration is 2m/s2

Dont Know its right or no

Answer 2

Answer:

speed= acceleration /time

let acceleration be x

speed =6m/s

time = 3s

so, 6m/s=x/3s

x= 6×3

=18m

acceration is 18m
