Answer:
25/9 m/s2
Explanation:
v= u +at
u= 0 as the car started from rest
t= 12 sec
120x 5/18 ( converting kmph to mps)= ax 12

Answer:
2.8
Explanation:
initial velocity is 0m/s. final velocity is 120km/h which equals 33.3 m/s. time taken is 12s. change of velocity is final minus initial velocity which is 33.3-0= 33.3m/s. Acceleration is time rate of change of velocity. so 33.3/12= 2.78 approx.
