In the s- t equation (s = 10 + 20 t - 5t2 ), match the following columns and mark the correct option from the codes given below.Codes A   B  C

At t=3 s,s=10+20(3)-5(3)2=25 unit   at t=0, s=10 unit so distance travelled=25-10=15 unit.    v=dsdt=20-10tAt t=4 s,v=20-10(4)=-20 unit      a=dvdt=-10 units Hence, A →q, B →s, C →p.
