Question

a cannon fires a cannon ball of mass 10 kg at a velocity of 100 m/s and recoils at a velocity of 2 m/s. what is the mas of the cannon?

Answer 1

Explanation:

ANSWER

Since there is no external force overall momentum of the system is constant which is zero.

⇒Mv

1

+mv

2

=0

⇒1000(v

1

)+10(100)=0

⇒v

1

=−1m/s

Answer 2

Since there is no external force overall momentum of the system is constant which is zero.

$</p><p> ⇒Mv 1+mv 2 \\ </p><p> =0 \\ </p><p> ⇒1000(v 1 )+10(100) =0</p><p> \\ ⇒v 1</p><p> \\ =−1m/s</p><p></p><p>$

So, cannon will recoil at the speed of 1m/s
