Question

A person moves along a circular thread with speed 10 metre per second . He covers one cycle in 10 minutes .The person is now challenged to complete it in half the time .What should be the constant acceleration that the person should maintain to complete his challenge ? Assume he is starting from rest.​

Answer 1

here is the solution for your question

Answer 2

Answer:

2/15

Explanation:

u=0 speed = 10 m/s  time = 10 minutes = 600 s

distance = speed * time

                  10*(10*60)

distance = 6000 m

half the time = 300 s

s=ut+ 1/2 (a)(t^2)

6000=0+1/2(a)300^2

12000/90000 = a

a= 2/15
