Question

a circular track has a circumference of 3140 with ab as one of the diameters . a scooter is moving from A to B along a circular path find his distance and displacement .what will be the displacement if it covers three quarters of the circle ​

Answer 1

Answer:

Explanation:

If the circumference is 3140 metres and AB is the diameter.

Then the Distance from A to B would be half the circumference i.e. 31402 1570 metres.

Now,The units are Distance 1570 m

Speed 10 m/s

So Time- Distance Speed 1570 ÷10= 157 seconds

And the Displacement is the Diameter.

So,π=Circumference ÷Diameter πx Diameter= Circumference

Diameter =Circumference÷π

(To make things Simpler are taking the first Three 3 digits of pi i.e. 3.14 as 22/7- 3.1415.....)

=3140÷ 3.14

=>3140÷3.14= 1000

So the Displacement or Diameter= 1000 Metres

And the Time 157 seconds.
