# Rotational motion: conservation of angular momentum

An asteroid of mass 8.10 x 10^7 kg traveling at a speed of 44 km/ s relative to the Earth hits the Earth at the equator. It hits the Earth tangentially and in the direction of the Earth's rotation. Use angular momentum to estimate the fractional change in the angular speed of the Earth as a result of the collision.
