Consider an object travelling in a semicircular path from point O to point P in 5 second, as shown in the figure. The average speed is |
|
Answer» 1) Average velocity = Total Displacement Total time Here, Total displacement is equal to "10cm" Because it is the shortest distance And , Total time is "5 sec" by putting this values in formula you will get 2cm/s 2) Average Speed = Total distance travelled Total time taken Total distance for a circle =2πr but here , distance will be 2πr/2
By putting this values in the formula you will get πr /5 = 2π |
