A bungee cord has a spring constant of 82.5 N/m. After jumping, a person oscillates with a period of 7.50 s. What is the mass of
Arada [10]

Answer:

Explanation:

T = 2π √ (m/k)

T / 2π = √ (m/k)

T√k = 2π √m

(T√k) / 2π = √m

( (T√k) / 2π)^2 = m

m = ( (7.5√82.5) / 2π)^2

m = 117.66 Kg

The coefficient of linear expansion of steel is 12 × 10-6 K-1 . What is the change in length of a 25-m steel bridge span when it
Westkost [7]

Answer:

0.012-m

Explanation:

∆L = α × Lo × (T-To)

α is the coefficient of linear expansion = 12 × 10-6 K-1

Lo = Initial length = 25-m

∆L = Change in length

(T-To) = 40 K

∆L = 12 × 10-6 × 25 × 40

∆L = 0.012-m

A student has a weight of 655 N. While riding a roller coaster they seem to weigh 1.96x 103 N at the bottom of a dip that has a
Nadya [2.5K]

Answer:

The speed of the roller coaster at this point is 18.74 m/s.

Explanation:

Given that,

Weight of the student, W = 655 kg

Weight of the roller coaster, F=1.96\times 10^3\ N

Radius of the roller coaster, r = 18 m

At the bottom of the loop, the weight of the roller coaster us given by :

F=W+\dfrac{mv^2}{r}

If m is the mass of the roller coaster,

W=mg

m=\dfrac{W}{g}

m=\dfrac{655}{9.8}

m = 66.83 kg

So,

F=W+\dfrac{mv^2}{r}

v=\sqrt{\dfrac{(F-W)r}{m}}

v=\sqrt{\dfrac{(1.96\times 10^3-655)\times 18}{66.83}}

v = 18.74 m/s

So, the speed of the roller coaster at this point is 18.74 m/s. Hence, this is the required solution.
