A small 21 kilogram canoe is floating downriver at a speed of 3 m/s. What is the canoe's kinetic energy?
astraxan [27]
The formula for finding the kinetic energy of an object is:
KE = 0.5MV^2,
Where:
M= Mass
V = Speed
From the information given above,
M = 21 kg
V = 3 m/s
KE = 0.5 * 21 * 9 = 94.5
Therefore, the canoe's kinetic energy is 94.5 J

Ratling [72]

Answer:

Mg(s) + H₂SO₄(aq) → MgSO₄(aq) + H₂(g)

Explanation:

Magnesium is a solid metal and sulfuric acid is aqueous (cuz all acids are aqueous)

When they react the salt formed is also in aqueous form and a precipitate of hydrogen is given off. hence H is a gas.
