The distance travelled by A is calculated as SA' = 10t (velocity is given as 10m/s)
and that of B is calculated as SB'
(As, A = Tan45° = 1)
Initially A is 10.5 m ahead of B, thus we get
SA + 10.5
Thus we get the equation as
t = 21 sec.
Hence, Both start moving at time t=0 in the same direction along a straight line. The velocity-time graph of two cars is shown in the figure. The time when the car B will catch the car A, will be 21 sec.
Hope its helpful for you.
