Question

Plzz help. All three questions​

Answer 1

a)The distance and displacement at A is pie*r

•Since , it is a CIRCULAR object.

•If it takes to cover the distance it should COMPLETE the path.

We know that,

•CIRCUMFERENCE OF A CIRCLE IS 2pie*r

Where,

•r is the RADIUS of the CIRCULAR PATH

BUT,

•The angle between O to A is 180degrees

.

•So ,the FORMULA is PIE*RADIUS

b)After it travels to 270degrees means

•Theta=270=180+90 degrees

Therefore,

•We have add 90degrees to the previous problem ,then

•DISTANCE =(pie+90)*r

c)Then it reaches the POINT “O” takes 2pie*r distance

Since,

•We have CIRCUMFERENCE of a CIRCLE IS 2pie*r.

•Therefore,DISTANCE =2pie*r

•Where, “r” is the radius of the CIRCULAR PATH.
