Question

A particle completes a semi
circular path of radius 10M in
10s. Find the ratio of speed to
linear velocity​

Answer 1

Answer:

Speed = distance/ time

= perimeter of semicircle/ time

= pi*R + 2R/ time

= 10( pi + 2)/ 10

= 10 ( 3.14+ 2)/ 10

= 5.14 m/s

Velocity= displacement/ time

= shortest distance across two points/ time

= 2R/ time

= 20/ 10

= 2 m/s

Therefore ratio= 5.14/2= 2.57
