Solution-
d1+d2+d3
d1 = 1/2*a*t^2 = 1/2*1.3*12*12 = 93.6m
d2 = v = at = 1.3*12 = 15.6 m
d2 = 15.6*22 = 343.2
d3 = Now slowing down. v^2 = u^2 - 2 a s
v = 0 so s = (15.6)^2 / 2.6 = 170.352m
total distance = d1+d2+d3 = 607.152 m
b) The time of last one. v = u-at
So t = u/a = 15.6 / 1.4 = 11.14 s
Now total time = 12+22+11.14 = 45.14 s
avg velocity = total distance/ total time = 13.45 s
