A)What is the acceleration at 1 second? Answer in units of m/s 2.

B) What is the velocity at 2 seconds?
Answer in units of m/s.

C) What is the position at 2 seconds?
Answer in units of m

Acceleration at 1 second= 1.5m/s/s

Velocity at 2 seconds = 3m/s

Position at 2 seconds= 3 meters

Explanation:

s=1/2(v+u)t

S= displacement

V= final velocity

U=  initial velocity

t= time

v= 3 m/s

u= 0 m/s

t= 2 seconds     3m/s/2=1.5m/s x2 s = 3 meters
