Question
I walk 450 steps at 25 degrees south east. Then 750 steps 72 degrees north of west and lastly 700 steps south of west. What will be my orientation and how many steps should I take to come back to starting point Use the following equations
Equations:
Vector components, standard Cartesian plane:
Vx= V cos 8
Vy = V sin 0
Constant linear acceleration:
V = Vo + at
Projectile motion:
X = Xo + Voxt
Rotational motion:
0 = s/r
@= @o + at
Frictional force:
w = v/r
Newton's Second Law of motion:
Centripetal force:
Use g
d = do + Vot + ½ at²
Gravitational force, or weight:
=
Vx² + Vy² = V²
y = yo + Voy - 1/2 gt²
360⁰ = 2n radians
a = aT/r
000+ wot + ½ at²
tan 8 = Vy/Vx
v² = vo² + 2a(d-do)
Vy = Voy -gt
ac = v²/r = rw²
w² = wo² + 2a(0 - 0)
ΣF = ma
Fg = mg
Ff = µFn
Fc = mv²/r
10.0 m/s² for the acceleration due to gravity near the surface of the earth.
