QB2-CONSTANT and VARIABLE ACCELERATION (a) A train starts from rest in one station, accelerating uniformly at 0.32 ms - for 2 minutes, then travels at a uniform speed for 4 minutes and finally retards uniformly for 1 minute to rest in the next station. What is the top speed attained and how far apart are the stations? (5 marks) (b) The acceleration of a particle moving along x-axis is given by a=6 Vx m/s?. When t=2 sec, the displacement x = 27 metres and the velocity v= 27m/s. Calculate the velocity and acceleration of particle when t-4sec. (5 marks)
