Physics

Question 1

finding R

Answer 1

R squared= x squared + y squared

Question 2

a angle under R

Answer 2

tan(a) = y/x

Question 3

finding R when non- parallel

Answer 3

R squared = F1 squared + F2 squared - 2 times F1 times F2 times cos(180 - whole angle)

Question 4

finding x using R and angle a or b

Answer 4

x= R times cos a = R times sin b

Question 5

finding y using R and angle a or b
