F=MA F is force- we are going to solve for F M is mass- quantity of matter that takes up an object A is acceleration- change in velocity F=MA F=(0.25 kg)(196 m/s^2) F= 49 N (newton-SI unit for force) Hope this helps!
49N is the force needed to give a .25 kg arrow an acceleration of 196m/s2. F =ma ⇒ =( 0.25kg)(196m/s2) = 49N if the arrow is shot horizontally where the applied force is entirely in the x-direction.
