Answer:

29u

Step-by-step explanation:

a = (V-U)/t = (1.2u-u)/10 = 0.02u

D1: V₀t+0.5at² = (u)(10)+(0.5)(0.02u)+(10)(10) = 11u

D2: (V)(t) = (1.2u)(15) = 18u

D = D1 + D2 = 29u

For first half

  • Initial velocity=u
  • Final velocity=v=1.2u
  • Time=10s

We need acceleration first

  • a=(1.2u-u)/10
  • a=0.2u/10
  • a=0.02u

So distance traveled (Apply second equation of kinematics

  • s=10u+1/2(0.02u)(10)²
  • s=10u+2/2×100/100×u
  • s=11u m

For second half

No acceleration

Distance=Speed×Time

  • 1.2u(15)
  • 18u m

Total distance

  • D=11u+18u
  • D=29u m
