ANSWER:

1) Back word     2) 2197 kg

EXPLANATION:

recoil (regularly called knock back, kickback or basically kick) is the retrogressive development of a firearm when it is released. so when the cannon is fired  the bullet will move forward and the cannon will move backward


The power of gravity on the moon is 1.6m/s2. Along these lines, the mass of a protest that weight is 21,532, the mass of that question on the moon will be 2197 kg.

Answer

1. According to Newton’s 3rd law, the canon will want to travel backward

2. 2197 kg

Explanation

In Newton’s 3rd law, forces occur in pairs thus every action has an equal and opposite reaction. For example, when firing a gun the bullet is set to air using the force of burning gun powder  and the gun itself recoils backward.

When converting Newton to kilogram, one Kilogram is equal to 9.81 Newton. To change Newton to Kilogram, we divide the value of Newton by 9.81, where as to convert kilograms to Newton, we multiply the value of kilograms by 9.81.In this case;

21532N to Kg= 21532/9.81 =2197 kg
