Find the acceleration of a hamster when it increases its velocity from rest to 10 in 2.4

acceleration is change in velocity over change in time: ?v/?t where ?v is change in velocity and ?t is change in time in seconds.
the change in velocity is the difference between the final and initial velocities i.e. from rest to 10. If 10 is in m/s, then ?v = final velocity - initial velocity = 10m/s - 0m/s = 10m/s.
if 2.4 is in seconds, then simply divide this into 10m/s to get your acceleration;
(10m/s)/2.4s = 4.17m/s squared.
