The object's final velocity, given the data is 10.5 rad/s
This is defined as the rate of change of velocity which time. It is expressed as
a = (v – u) / t
Where
The following data were obtained from the question
The final velocity can be obtained as follow:
a = (v – u) / t
0.75 = (v – 1.5) / 12
Cross multiply
v – 1.5 = 0.75 × 12
v – 1.5 = 9
Collect like terms
v = 9 + 1.5
v = 10.5 rad/s
Thus, the final velocity of the object is 10.5 rad/s
