Q22 of 59 Page 254

An electric engine has a velocity of 120 kmh-1. How much distance will it travel in 30s?

Now, = 120 kmh-1

= ms-1


= ms-1


Now, time = 30 s


Hence, Distance = × time


=


= 1000 m


= 1 km


Hence, the distance travelled by the electric engine in 30 s is 1 km.

Two trains A and B of length 400 m each are moving on two parallel tracks with uniform speed of 72 kmh-1 in the same direction with A ahead of B. The driver of B decides to overtake Aand accelerate by 1 ms-2. If after 50 s, the guard of B just passes the driver of A, what was the original distance between them?
