Question

A body is tied to a string and is given a circular motion with a velocity v and radius r . The magnitude of its acceleration is

Answer 1

Answer is given above...

Answer 2

Answer:

Two Type of Acceleration

1. Centripetal which towards centre
2. Tangential which towards Velocity

Both Acceleration perpendicular to each other

acp - v^2/r, vw, w^2r. (v=wr)

v- linear Velocity

w - angular Velocity

at - alpha R

alha - angular acceleration

Net acceleration.

A = √acp^2 + at^2

Angle fromHz - tan0 = at/acp

Case 1

In Uniform Circular Motion

Speed - constant

at = 0

acp not 0

Anet = acp

Case 2

Non Uniform Circular Motion

v not constant

at as well as acp not 0
