Expert Answer

use the formula acceleration = change in velocity  /  time taken , this will give acceleration

first for the first 6 sec. use the formula s=ut + at2 /2 , u is the initial velocity, t is time , a is acceleration

for the next 4 sec. use the formula d = s x t , where s is the speed and t is the time = 4 sec
