A meteoroid changed velocity from 5.3m/s to 2.8 m/s in 0.3 seconds. What is the acceleration of the meteoroid ?

#1**0 **

-2.5/0.3^{2}

-2.5/0.09

-2.5/0.09 = 27.7777777777777778

m / s^{2}

So the acceleration of the meteoroid is -27.78m/s^{2}

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
