Hey there!
1kmph = 5/18 m/s
Now, Initial velocity ( u )= 20kmph = 100/18 m/s
Final velocity ( v) = 50kmph = 50*5/18 = 250*18 m/s.
Acceleration = v - u / t
=[ 250/18 - 100/18 ] / 10
= 150/18 / 10
= 150/180
= 15/18
= 5/6 m/s²
1kmph = 5/18 m/s
Now, Initial velocity ( u )= 20kmph = 100/18 m/s
Final velocity ( v) = 50kmph = 50*5/18 = 250*18 m/s.
Acceleration = v - u / t
=[ 250/18 - 100/18 ] / 10
= 150/18 / 10
= 150/180
= 15/18
= 5/6 m/s²
