A meteoroid changed velocity from 5.3m/s to 2.8 m/s in 0.3 seconds. What is the acceleration of the meteoroid ?
-2.5/0.09 = 27.7777777777777778
m / s2
So the acceleration of the meteoroid is -27.78m/s2
Hope this helps!
Acceleration = change in velocity/change in time
= (vf - vo) / time
a = (2.8 -5.3) m/s / (.3 sec) = - 8.333 m/s^2
