Homework Statement
Suppose a 5.7×10^10 kg meteorite struck the Earth at the equator with a speed 3.0×10^4 m/s, making a 45 degree angle (see figure) and remained stuck.By what factor would this affect the rotational frequency of the Earth (1rev/day)?
Homework Equations
It seems like an inelastic collision and I suppose that the following equation will also be used:
w_f = v/R
(w_f - w_i)/w_i
The Attempt at a Solution
I figured out the initial angular velocity of Earth but don't know what the final angular velocity will be because I don't think it will be as easy as plugging in numbers on w_f= v/R. The mass of the meteorite must be considered at some point, right?
w_E = (1rev/day)(2pi/1 rev)(1 day/24hr)(1hr/3600s)=7.27^-5 rad/s
