If an object is moving at #4 m/s# and accelerates to #6 m/s# over 3 seconds, what was the object's rate of acceleration? Physics 1D Motion Acceleration 1 Answer ali ergin Apr 12, 2016 #a=2/3 m/s^2# Explanation: #v_i=4 m/s" initial velocity of object"# #v_l=6 m/s" last velocity of object"# #t=3 s# #a=?" acceleration of object"# #"the object's rate of acceleration is given as "a=(Delta v)/(Delta t)# #Delta v=v_l-v_i=6-4=2 m/s# #Delta t=3-0=3# #a=2/3 m/s^2# Answer link Related questions Why is acceleration measured in meters / seconds squared?
