Simply apply the formula of acc.
A= v-u/t
U get
A= 60-20/6
A=40/6
A=6.10 m/s^-2
A= v-u/t
U get
A= 60-20/6
A=40/6
A=6.10 m/s^-2

A=v-u/t
=60-20/6
=40/6m/s^2
=60-20/6
=40/6m/s^2
Sorry the answer is wrong..first we have to convert the km /h to m/s by multiplying it by 5/18....sorry i couldnt edit the answer beacuse the edit option is not coming...
20km/h will be 20×5/18=50/9m/s and 60km /h will be 60×5/18= 50/3 m/s
Now a=v-u/t =(50/3-50/9)/6 =(150- 50/9)/6 =(100/9)/6 =100/9×1/6= 50/27m/s^2
Hope u got it
