Given:
The mass of the object is m = 9.5 kg
The force acting on it is F = 14.2 N
The time duration is t = 3.6 s
The initial speed is
To calculate the final speed.
Step-by-step explanation:
An impulse of an object is calculated as
It can also be written as
So, the final velocity can be calculated by equating both the formula
On substituting the values, the final speed will be
Thus, the correct choice is E
