Question

A body covered a distance of z metre along a semicircular path. Calculate the magnitude of displacement of the body, and the ratio of distance to displacement.​

Answer 1

Answer:

11:7

Step-by-step explanation:

Let radius of semicircular be r

πr = z =>r = z/π => 2r = 2z/π

Distance=πr=z

Displacement=2r=2z/π

Distance: Displacement

=z:2z/π

=1:2/π

=π:2

=22/7:2

=22:14

=11:7
