Here we have, speed = 3×108 m/s
Time = 5 minute = 5 × 60 s = 300 s
Using, Distance = Speed × Time
⇒ Distance = 3 ×108 × 300 m = 900 × 108 m= 9.0 × 1010 m
Question
During an experiment, a signal from a spaceship reached the ground station in five minutes. What was the distance of the spaceship from the ground station? The signal travels at the speed of light, that is, 3×108 ms−1.

A driver of a car travelling at 52 kmh-1 applies the brakes and accelerates uniformly in the opposite direction. The car stops after 5 s. Another driver going at 34 kmh-1 in another car applies his brakes slowly and stops in 10 s. On the same graph paper, plot the speed versus time graphs for two cars. Which of the two cars travelled farther after the brakes were applied?
