The recoil speed of the cannon is 3 m/s.
<u>Explanation:</u>
Law of conservation of momentum is used to find the recoil speed of the cannon.
m₁v₁ = -m₂v₂
m₁= mass of clown = 100 kg
v₁ = speed of the clown = 15 m/s
m₂= mass of the cannon = 500 kg
v₂ = speed of the cannon = ?
Plugin the values, we will get,
v₂ = m₁v₁ / -m₂ = -100×15/ 500 = -1500 / 500 = 3 m/s
So the recoil speed of the cannon is 3 m/s.

Answer:
B. 3 m/s
Explanation:
We can solve the problem by using the law of conservation of momentum; in fact, the total momentum before and after the collision must be conserved. So we can write:
where:
m1 = 150 kg is the mass of spaceship 1
m2 = 150 kg is the mass of spaceship 2
u1 = 0 m/s is the initial velocity of spaceship 1
u2 = 6 m/s is the initial velocity of spaceship 2
v is the velocity of the two ships after they collide and stick together
Solving for v, we find:
let the moles of chlorine-35 is n1 and chlorine-37 is n2
now we will use the formula of average atomic mass
here let say
so here since ratio of moles of chlorine 35 and chlorine 37 is more than 1 so chlorine 35 is more in the proportion in this mixture so <em>there is most chlorine atom consist of 18 neutrons</em>
