Homework Statement
1. Homework Statement
The velocity of the Moon relative to the center of the Earth can be approximated by varrowbold(t) = v [−sin (ωt) xhatbold + cos (ωt) yhatbold], where v = 945 m/s and ω = 2.46 multiplied by 10−6 radians/s. (The time required for the Moon to complete one orbit is 29.5 days.) To approximate the instantaneous acceleration of the Moon at t = 0, calculate the magnitude and direction of the average acceleration during the following two time intervals.
(a) between t = 0 and t = 0.200 days
______ m/s
______ degrees (counterclockwise from the +x axis)
(b) between t = 0 and t = 0.0020 days
_____ m/s
_____ degrees (counterclockwise from the +x axis)
The Attempt at a Solution
When I try to solve for Vx and Vy I get the same result for each one, yielding zero, and if I try another method, i get very minute numbers. None of which appear to be correct. I'm at a loss for how to do this problem
