Answer 1

Answer:

$acceleration = \frac{(v - u)}{t}$

were,

v = final velocity

u = initial velocity

t = time

therefor ,

v=60km/hr= (60 X 10^3)/ (60x60)= 16.66m/sec

u=40km/hr = 40 x10^3/(60x60)=11.11m/sec

t =5sec

Now,

$= > a = \frac{16.66 - 11.11}{5}$

$= \frac{5.55}{5}$

$= 1.11m {s}^{ - 2}$
