Question

a car can accelerate at 2m/s2 how long will it take to speed up from 1m/s to 11m/s ?

Answer 1

Answer:

it will take 5 seconds

Explanation:

acceleration = (v-u)/t

2 = (11-1)/t

2= 10/t

2t = 10

t= 10/2 = 5 seconds

v= final velocity or speed

u= initial velocity or speed

t time taken
