Answer:

according to the graph

initial velocity of A = 30km/h

final velocity of A = 0 km/h

initial velocity of B = 0 km/ h

final velocity of B=. 20km/h

Explanation:

Distance travelled by object A

a=v/t = -3 m/s

--3

v² = u² + 2as

s= 900/6 =150 km

distance travelled by object B

a= v/t = 20/15 =1.6

s= 400/3.2= 125 km/h

time at which velocity are same at 7 hrs
