Aconstant force of 12n is applied for 3.0s to a body initially at rest. the final velocity of the body is 6.0ms–1. what is the mass of the body?

From the question,






Using Impulse, the product of the constant force, F and time t equals the product of the mass of the body and change in velocity.




This implies that





You can also use the equation of linear motion,






But
