Question

plzz answer it properly....

Answer 1

Hope u like my process
======================
Formula to be used :
------------------------------
v =u +at __
Where
V = final velocity
U = initial velocity
A = Acceleration
T = time taken
________________
At initial 2 sec,

V = 33.6 km/hr =33600/3600 =9.33m/s
U = 30 km/hr =30000/3600 =8.33m/s
T = 2 second

A = (V - U) /T = (9.33 - 8.33)/2 = 1/2
= 0.5 m/s²
_______________
At next 2 sec,

V = 37.2 km/hr = 37200/3600 =10.33m/s
U = 33.6 km/hr = 9.33 m/s
T = 2 second

A = (V - U) /T = (10.33-9.33)/2 =1/2
=0.5 m/s²

++++++++++++++++++++++++++++
Thus required Acceleration of vehicle =
0.5m/s²

Yes, the Acceleration is Uniform!!
