The exam is worth 100 points. Some of the equations are given below.
1 dimensional kinematic Equations: vf = vi+at
vf2 = vi2 + 2a(xf-xi)
xf = xi+ vit+ 1/2axt2
Projectile Motion vfy = viSin
vfx = vix
xf = xi+ vixt vix = viCos
vfy2 = viy2 + 2ay(yf-yi)
yf = yi+ viyt+ (½)ayt2
Newtons Law ΣFx = max
ΣFy = may
Centripetal/ radial acceleration ac or ar = v2/r;
v=r ; at r
A= Ax i +Ayj || Tan(θ)= VAB +VBC=VAC Date: 6/12/2011 Page 1 ...
