10 m/s in 10
3. a car accelerates from 0 m/s to 50 m/s in 10 seconds. what is the acceleration?

5ms⁻²

Explanation:

Given that,

Initial velocity of car (at t=0) u=0 m/s

Final velocity of car (after 10 sec) v=50 m/s

Time taken (t)= 10 sec.

acceleration(a)=?

now,

v = u + at

at = v-u

a=  (v-u) / t

a= (50-0) / 10

a = (50/10)

a=5 ms⁻²

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
