Explanation:
Hey there !
Initial Velocity = u = 0
Final velocity = v = 72 km/hr = 72 x 5/18 = 20 m/s
Time = t = 10 sec
Acceleration = a
Equation of motion :-
v = u + at
20 = 0 + 10a
a = 20/10
a = 2 m/s²
displacement = distance traveled = s
Equation of motion :-
v² - u² = 2as
20² = 2 × 2 × s
400 = 4s
s = 400/4
s = 100 m
Average velocity = displacement / time
= 100 / 10
= 10 m/s
Hope this helps you !

acceleration = changes in velocity/time
U =0m/s
V =72*5/18 = 20m/s
T = 10 sec
a= 20-0/10
a = 20/10
a= 2 m/s^2
Hope it helps you
