It is given that,
Mass of the object, m = 0.5 kg
A force is applied for 27 ms.
Initial speed of the object, u = +14 m/s
Impulse of the force, J = 32.4 N-s (in negative direction)
Let v is the velocity of mass in x direction. We know that the impulse of an object is equal to the change in momentum. It is given by :
v = -67 m/s
So, the velocity of the mass is 67 m/s and it is in negative x direction.
