October 08,2025 11:19 PM

Q- At t = 0, car A starts from rest at point 1. It moves with an acceleration of 0.4 t m/s^2. At the same time, car B starts from point 2, which is 225 m ahead, with a constant acceleration of 2 m/s^2 in the same direction. Find: 

(a) Speed of car A at the end of the 225 m section. 

(b) Time to travel 225 meters by car A. 

(c) Magnitude of car A’s acceleration as it reached point 2. 

(d) How far has car B moved when car A reached point 2?
