Please help!
Explanation:
Answer:
frequency = 0.5 Hz and speed = 2 m/s
Explanation:
Given that,
The period of a wave, T = 2 s
Wavelength, 
If f be the frequency. So,
f = 1/T
Speed of a wave is given by :
So, the frequency of the wave is 0.5 Hz and speed is 2 m/s.
Answer:
497.6 N
Explanation:
From the question,
The net force on the skydiver = weight of the skydiver- the resistive force of air
F' = W-F...................... Equation 1
Where W = weight of the skydiver, F = resistive force of air.
But,
W = mg................ Equation 2
Where m = mass of the skydiver, g = acceleration due to gravity.
Substitute equation 2 into equation 1
F' = mg-F............ Equation 3
Given: m = 87 kg, F = 355 N, g = 9.8 m/s²
Substitute these values into equation 3
F' = 87(9.8)-355
F' = 852.6-355
F' = 487.6 N
Answer:
a = -5/6 m/s²
Explanation:
v² = u² + 2as
a = (v² - u²) / 2s
a = (0² - 5²) / 2(15)
a = -5/6 m/s²
This assumes the initial velocity was in the positive direction.
