Question

your are spining a ball a hached to a string such that udsicrible a circle of radiues 75cm, at velocity 1.5m/S.what is acceleration of ball​

Answer 1

first we convert cm into m .75m

2πr=2*22*.75 = 2*22*75

7 7*100

we will reduce them =3 = .428571

7

given =) a=? u=0 v=0.428571 Velo=1.5m towards S

a=v-u = .428571-0. =.428571

t t t

at=.428571
