Answer 1

Answer:

As explained.

Explanation:

Angular velocity shows how fast a particular object does rotate or revolve with being relative to another point, that is how fast the angular position or rather specifically the orientation of an object is changing with time. There are basically two types of angular velocity namely orbital angular velocity and spin angular velocity.

The derivation.

Now suppose a particle is rotating to act on a body to rotate it in a circular Motion with uniform angular velocity. Let the mass be m, radius be r angular velocity w.

As acceleration towards of the particle towards the centre along radius is w²r

Necessary centripetal force

F=ma= mw²r = mv²/r =mvw

Answer 2

Answer:projectile motion Explanation: an object is in flight after being thrown with some velocity is called projectile and its motion is called projectile motion Parameter of projectile motion 1.Horizontal range 2.maximum height 3. time of flight
