To develop this problem it will be necessary to apply the concepts related to the frequency of a spring mass system, for which it is necessary that its mathematical function is described as

f = \frac{1}{2\pi} \sqrt{\frac{k}{m}}

Here,

k = Spring constant

m = Mass

Our values are given as,

m = 35g = 35*10^{-3}kg

f = 1 Hz

Rearranging to find the spring constant we have that,

k = (2\pi f \sqrt{m})^2

k = 4\pi^2 f^2 m

k = (4) (\pi)^2 (1) (35*10^{-3})

k = 1.38N/m

Therefore the spring constant is 1.38N/m

11m if you add 6+5 you get 11 but of course you need the “m” in the mix so 11m but correct me if I’m wrong.

A bus driver drove from Philadelphia to Washington DC. He drove the first 100km in 2 hours, the next 55km in 1 hour, and the fin
Alla [95]

Answer:

b. 46 km/hr

Explanation:

Applying,

S' = d'/t'................... Equation 1

Where S' = Average speed of the bus, d' = Total distance covered by the bus, t' = Total time taken.

From the question,

d' = (100+55+75) km = 230 km

t' = (2+1+2) = 5 hours

Substitute these values into equation 1

S' = 230/5

S' = 46 km/hr.

Hence the correct option is b. 46 km/hr
