The equation only is true for objects with negligible air resistance. A feather does not have this property.
Using the equation shown:
50 = -16t^2
t^2 = 50/16 = 3.125
t = sqrt(3.125) = 1.77 seconds

What are the missing numbers in this series: 10,16,21,26,31,
kati45 [8]

Answer:

38

Step-by-step explanation:

16 - 10 = 6

21 - 16 = 5

26 - 21 = 4

31 - 26 = 5

31 + 6 = 38

The next missing number is 38.

From there, continue the pattern.

A spring has natural length 0.75 m and a 5 kg mass. A force of 8 N is needed to keep the spring stretched to a length of 0.85 m.
I am Lyosha [343]
Use Hooke's law to find the spring constant. If it takes 8N to stretch the spring by 0.1m, then

8\text{ N}=k(0.1\text{ m})\implies k=80\dfrac{\text N}{\text m}

I'm going to assume the spring is fixed to a ceiling, and that any stretching in the downward direction counts as movement in the positive direction. The spring's motion is then modeled by

y''(t)+80y(t)=0

where y(t) is the position of the spring's free end as it moves up and down. Solving this is easy enough: the characteristic solution will be

y(t)=C_1\cos4\sqrt5t+C_2\sin4\sqrt5t

Given that the spring is stretched to a length of 1m (a difference of 0.25m from its natural length), and is released with no external pushing or pulling, we have the two initial conditions y(0)=\dfrac14 and y'(0)=0.

y(0)=\dfrac14\implies\dfrac14=C_1\cos0+C_2\sin0\implies C_1=\dfrac14
y'(0)=0\implies 0=-4\sqrt5C_1\sin0+4\sqrt5C_2\cos0\implies C_2=0

So the spring's motion is dictated by the function

y(t)=\dfrac14\cos4\sqrt5t
