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:
a.$4,704
Explanation:
Depreciation rate applicable for 2nd year as per MACRS 5 year class property = 32%
So, Irene cost recovery deduction = $21,000 * 32% * 70% = $4,704
Hence, the cost recovery deduction for Irene in 2020 is $4,704.
