Plz for 1. when a cannon is fired, the projectile moves forward. according to newton's 3rd law, the cannon will want to travel 2. an object has a weight of 21,532 n on earth. what is the mass of the object? 2,200 g 2,197 kg 215,000 kg none of the above

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
