a bus starts from rest. if the acceleration is 2meter per second, find distance traveled and velocity after 2 sec.​

vf= 4 m/s
d= 4 m

Explanation:
It is given that the initial velocity is 0 m/s, the acceleration is 2 m/s^s, and the time is 2 seconds. To find final velocity, use the kinematics equation vf=vi+at.
final velocity=0+(2*2)=4 m/s
For distance, use the kinematics equation vf^2=vi^2+2ad.
4^2=0^2+(2*2*d)
16=4d
distance=4 meters.

Parenthesis are used to distinguish the number of polyatomic ions from the number of atoms. hopefully this ! : )
