Answer:

aati hu mata jiii are in thi lele me jyoti ki id se

INITIAL VELOCITY = U = 54 km/h = 15 m/S

FINAL VELOCITY = V = 72 km/h = 20 m/s

TIME = T = 5 SECONDS

FINDING ACCELERATION (A)

------------------------------------------

V = U + AT. (FIRST EQ. OF MOTION)

20 = 10 + A*5

5A = 20 - 10

5A = 10

A = 10/5

A = 2 m/s2

THEREFORE,

ACCELERATION = 2 m/s2
