Question

Write five differences between distance and displacement.
An object moves 60 m due east and then 80 m due north. Find the distance travelled and the magnitude of displacement.
In game of cricket, the length of pitch is 18 m. After completing one run, a batsman turns back but gets run out when he is halfway through his second run. Calculate the distance travelled and his displacement.
Distinguish between rest and motion.
Mass is a scalar quantity. Give reason.
What is the displacement of the earth when it completes one revolution around the sun?
A car travels 20 Km at a uniform speed of 40 Km/h and the next 20 Km/h at a uniform speed of 60 Km/h. Find its average speed.
Distinguish between speed and velocity.
A train takes 2 hrs to reach station B from station A, and then 3 hrs to return from station B to station A. The distance between the two stations is 200 Km. Find
i The average speed ii The average velocity of the train
A scooter acquires a velocity of 54 Km /h in 15 sec just after the start. Calculate the acceleration of the car.

Answer 1

Answer:

The greatest possible acceleration and deceleration that the train may have is a and its maximum speed is v. find the maximum time in which the train can get from one station to the next if the total distance between the stations is s. the train starts at rest and comes to a stop at it's destination.
