Hello, for this applicate formula:
Vf² = Vo² + 2gh
Data:
Vf = Final Velocity = ¿?
Vo = Initial veloctiy = 0 m/s
g = Gravity = 9,81 m/s²
h = Height = 5 m
Replacing according our data:
Vf² = 0 m/s² + 2(9,81 m/s²)(5 m)
Vf² = 98,1 m²/s²
Vf = √98,1 m²/s²
Vf = 9,9 m/s
The final velocity will be <u>9,9 meters per second.</u>
Answer:
Average speed = 40.50 km/h (Approx)
Explanation:
Distance = Time × Speed
Total distance = (40/60) 50 + (8/60) 70 + (35/60) 35
Total distance = 33.33 km + 9.33 km + 20.17 km
Total distance = 62.80 km
Average speed = Total distance / Total time taken
Average speed = 62.80 / [(40+8+35+40)/60]
Average speed = 62.80 / 1.55
Average speed = 40.50 km/h (Approx)

Answer: 12.5m
Explanation:
Given the following :
Flagpole makes 20 complete vibrations in 10 seconds
Velocity (V) of vibration = 25m/s
Find the wavelength of vibration (λ) =?
Frequency is number of complete oscillation per Second
Therefore ;
Frequency (F) = number of oscillations / time taken
F = 20 / 10 = 2Hz
Wavelength = Velocity / frequency
Wavelength = 25 / 2
Wavelength = 12.5m
