Answer:
The molecular formula for the compound is C4H8.
Explanation:
Emperical formula is CH2
Molar mass = 56 g/mol
Molar mass = (CH2)n
56 = (12 + 1×2)n
56 = (12 + 2)n
14n = 56
n = 56/14 = 4
Molecular formula = (CH2)n = (CH2)4 = C4H8
Answer:
Explained below
Explanation:
Newton's first law of motion: This law states that an object will remain at rest or continue in constant motion except it's acted upon by an external force. In projectile motion, the horizontal component of velocity will remain unchanged because we ignore air resistance since no force is acting in that horizontal direction.
Newton's second law of motion: This law states that force is the product of mass and acceleration. In projectile the force acts downwards, thus f = mg.
But g = a since internal forces will cancel out.
Thus, F = ma
<span>95m /2 = 47.5m
47.5m = Vocos38t
</span><span>Vy = Voy -9.8t
0 = Vosin38 - 9.8t
0 = Vosin38 - 9.8(47.5 / Vocos38)
0 = Vo^2(0.62) - 590.7

<span>Vo = 30.87 m/s
