Question

A body moves in a semicircular path it's diameten is 10cm
il calculate distance and discplacement.​

Answer 1

Answer:

distance is 15 and displacement is 0

Explanation:

This is baecause the object is moving in a partially circular motion so the initial and final point Is same...so displacement=0 and distance will 15+ πr*2

Answer 2

Answer:

we need to calculate the circumference.

And the formula fr that is 2πr

we know radius is 1/2 diametre. hence r = 5cm

we need to find circumference of semicircle. Which is

1/2*2πr.( 2 and 2 gets cancelled)

Hence u need to do π×5+10
