Explanation:
Parameters
Number of oscillation = 40 oscillations
Time of oscillation = 128s
Formular
Period (T) = <u>No of oscillation</u>
Time taken
T = <u>128</u>
40
T=3.2s
Answer:
10,600 m
Explanation:
Use range equation:
R = v₀² sin(2θ) / g
R = (433.0 m/s)² sin(2 × 64.8°) / (9.8 m/s²)
R = 14,700 m
The range is shortened by 28.1%.
0.719R = 10,600 m
