circular motion

circular motion 

projectile motion 

formula :

initial speed of the projectile :

 vxo=vo cos theta

 vyo=vo sin theta

speed of the projectile at arbitrary time:

 

vx=vxo

vy=vyo-gt

posotion of projectile at arbitrary time :

x=xo + vxo t

y=yo + vyo t - 0.5 gt

maximum height :

Hm =0,5  vyo*vyo/g

tm=0,5 vyo/g

range aand maximum range :

T=2tm

R=vxoT

Rmax =vyo*vyo/g

centripetal acceleration 

formula 

ac=fc/m

a=v*v/R

s=2*3,14*R

w=theta/T

v=s/T  

a=v*v/R
