worksheet Two ladybugs (A and B) are sitting on a wheel that is rotating at 1 rev./s. A 2 4 6 y x B Draw a x(t) graph for ladybug A Assume now that the wheel is rotating at f = 2 revs./s . Draw a x(t) graph for ladybug A make a list of all the parameters that are the same for ladybug A & B Write the equation of motion for ladybug A and ladybug B ; General equation: x(t) = A cos ( ω t + ϕ 0 )
worksheet The graph shows the x-position as a function of time of a ladybug on a wheel with constant angular velocity ω . Which of the following graphs is obtained if ladybug A sits closer to the rim of the wheel? -2 -1 0 1 2 0 0.5 1 1.5 2 2.5 Time -2 -1 0 1 2 0 0.5 1 1.5 2 2.5 -4 -2 0 2 4 0 0.5 1 1.5 2 2.5 -2 -1 0 1 2 0 0.5 1 1.5 2 2.5 -1 -0.5 0 0.5 1 0 0.5 1 1.5 2 2.5 -2 -1 0 1 2 0 0.5 1 1.5 2 2.5 A B C E D
