Homework Statement
A ladybug with a velocity of 10 mm/s [W] crawls on a chair that is being pulled with a velocity of 40 mm/s [40 degrees N of W]. What is the velocity of the ladybug relative to the ground?
Homework Equations
The Attempt at a Solution
finding the y-component
40(sin40) = 25.7
x-component requires the addition of two x-axis component vectors
40cos40 + 10 = 40.6
Now a² + b² = c²
25.7² + 40.6² = c²
c = 48.1mm/s
