Question

1) In one round trip a man travels 50km and then arrive back home. Find

a) Distance travelled

b) Displacement

2) A particle is moving in a circle of diameter 7m .Calculate the distance covered and the

displacement when it covers 3 revolutions

3)In a long distance race, the athletes were expected to take 4 rounds of the track such.that the line

of finish was same as the line of start. If the length of the track was 200m

a) what is the total distance to be covered by the athletes?

b) What is the displacement of the athletes when they touch the finish line?

c) Is the motion of the athletes uniform or non-uniform?

d) Is the displacement of an athlete and the distance moved by him at the end of the race equal?

4) A particle covers three quarters of a circle of radius r. What is the magnitude of displacement?(

Ans:1.41r)

5) A body travels a distance of 8m from A to B,then moves a distance of 6m at right angles to AB.

What is the total distance travelled and magnitude of displacement?​

Answer 1

Answer:

Explanation:

This is the explanation of question 1

a) Since the man goes & comes back he travelled twice the same path so it's dist travelled= 2×50=100

b) Since it's initial and final position are same so displacement=0
