Question

a child crawls 2.5 m directly to the east and then turns 25 degrease and crawls another 1.2 m. What is the magnitude of the childs displacement?

Answer 1

Draw the vectors over the x and y coordinates

Answer 2

Did you figure it out?

Answer 3

if you draw a diagram you will get a triangle with 2 sides and an angle known. solve for the bigger side and u will have your answer

Answer 4

This is the triangle now you can solve it

Answer 5

\[x ^{2} = (2.5)^{2} + (1.2)^{2} - 2(2.5)(1.2)(\cos 25)\]
x = 1.5 m

Answer 6

this should be the right answer
