Answer 11

2.54 cm

Question 12

1ft=______in

Answer 12

12

Question 13

Formula to find vector:
X=
Y=

Answer 13

x=Vcosø
y=vsinø

Question 14

V=10 m/s
Ø=30

Find x and y component.

Answer 14

x=VCosø=(10m/s)cos(30) = (10m/s)(√3 /2) = 5√3 m/s

Y=VSinø=(10m/s)sin(30)=(10m/s)(1/2)= 5m/s

Question 15

Weight of Object Formula

Answer 15

Fg = m x g

g = 9.81 m/s^2

Question 16

The force of gravity b/w 2 objects formula:

Answer 16

Fg = (G x m1 x m2) / (r^2)

G= gravitational force constant
6.67x10^-11 N•m^2 /kg^2

r= dance b/w m1 & m2
