Hi Friend

Change in velocity is called acceleration
so, a= v-u/t
a = 60-50/2
a = 10/2 = 5 km h^-2
a = 1.38 ms^-2

Initial velocity of the car = 50 km/h = 250/18 m/sec
Final Velocity = 60 km/hr = 300/18 m/sec
Now time taken = 2 sec
Acceleration = v - u/t
v - u = 300/18 - 250/18 = 50/18 m/sec
Acceleration = 50/18÷ 2 = 25/18 = 1.38 m/sec²
Final Velocity = 60 km/hr = 300/18 m/sec
Now time taken = 2 sec
Acceleration = v - u/t
v - u = 300/18 - 250/18 = 50/18 m/sec
Acceleration = 50/18÷ 2 = 25/18 = 1.38 m/sec²
