Answer:
The acceleration of the javelin during the throw, assume that it has a constant acceleration is: 377.92 m/s2
Explanation:
The first step is to get the velocity at which the javelin leaves the hand value (V):
V horizontal component:
Vh = V×cos(30) = 0.866×V
V vertical component:
Vv = V×sin(30) = 0.5×V
Using horizontal motion data:
r = v × t
50 = 0.866×V × t
t = 57.73/V
Use time gotten in the vertical motion equation:
s = u×t + a×t²/2
-2 = 0.5×V×57.73/V + (-9.8)×(57.73/V)²/2
V = 23.002 m/s
Now let´s get the acceleration of the javelin while throwing:
v² = u² + 2×a×s
23.002² = 0² + 2×a×0.7
a = 377.92 m/s²
Answer:
c. 179,811
Explanation:
The computation of the number of shares of stock sold for expansion is shown below:
The Number of shares is
= (Fund for growth + Legal and filing fees) ÷ Net price after underwriter spread
= ($6,800,000 + $352,000) ÷ (43 × (1 - 7.5%))
= $7,152,000 ÷ $39.775
= 179,811 shares
Hence, the correct option is c.
We simply applied the above formula so that the correct value could come
And, the same is to be considered
