What is the acceleration of a toy car that
starts from rest and has a speed of 0.12
m/s after 0.1 seconds?

Step-by-step explanation:

acceleration = DV/DT

DV= change in velocity ( Final velocity- initial Velocity)

DT= change in time (Final time - initial time)

initial velocity=0

initial time = 0

acc= (o.12m/s-0)/(0.1s-0)

acc= 1.2m/s^2

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
