Question

what is the force needed to give a .25 kg arrow an acceleration of 196m/s2?

Answer 1

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!

Answer 2

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.
