Many scientists believe that the dinosaurs were killed in a large-scale extinction event.
if a large meteor of mass 6.2 × 1010 kg and speed of 2.2 × 104
struck earth at that time, it
would alter the rotational velocity of the planet.
assuming the rotational speed after the meteor struck was (and still is) 1 rev/23.93 hours1
,
how long was a day before the meteor struck?
