If a 40 kg gymnast and a 400 kg sumo wrestler each dropped from 1 m above the trampoline, find the final position of each athlet
Tomtit [17]
When you drop an object from some height on the spring objects initial potential energy is converted to kinetic energy, this kinetic energy is then used to compress the spring. Once all the energy is used the spring stops compressing and starts oscillating. 
We need to find how much the spring compressed in both cases.
From the above analysis, we can conclude that potential energy in the gravitational field has to be equal to the potential energy of compressed spring.
mgh=\frac{1}{2}kx^2
We solve for x (in our case h=1):
mg=\frac{1}{2}kx^2\\
x^2=\frac{2mg}{k}\\
x=\sqrt{\frac{2mg}{k}}
Now we just have to plug in the numbers:
$$Sumo\ wrestler(m=400kg):x=\sqrt{\frac{2mg}{k}}=0.81m\\

$$ Gymnast(m=40kg):x=\sqrt{\frac{2mg}{k}}=0.26m\\

A rod 150 cm long and of diameter 2.0 cm is subjected to an axial pull of 20 kn. if the modulus of elasticity of the material of
Scilla [17]
Given:
rod of circular cross section is subjected to uniaxial tension.
Length, L=1500 mm
radius, r = 10 mm
E=2*10^5 N/mm^2
Force, F=20 kN = 20,000 N
[note: newton (unit) in abbreviation is written in upper case, as in  N ]

From given above, area of cross section = π r^2 = 100 π =314 mm^2
(i) Stress,
σ
=force/area
= 20000 N / 314 mm^2
= 6366.2 N/mm^2
= 6370 N/mm^2 (to 3 significant figures)

(ii) Strain
ε
= ratio of extension / original length
= σ / E
= 6366.2 /(2*10^5)
= 0.03183 
= 0.0318 (to three significant figures)

(iii) elongation
= ε * L
= 0.03183*1500 mm
= 47.746 mm
= 47.7 mm  (to three significant figures)

Diffraction gratings with 10,000 lines per centimeter are readily available. Suppose you have one, and you send a beam of white
ArbitrLikvidat [17]

The angles for the first-order diffraction of the shortest and longest wavelengths of visible light are 22.33 ⁰ and 49.46 ⁰ respectively.

<h3>Angle for the first order diffraction</h3>

The angle for the first order diffraction is calculated as follows;

dsinθ = mλ

sinθ = mλ/d

<h3>For shortest wavelength (λ = 380 nm)</h3>

d = 1/10,000 lines/cm

d = 1 x 10⁻⁴ cm x 10⁻² m/cm = 1 x 10⁻⁶ m/lines

sinθ = (1 x 380 x 10⁻⁹)/(1 x 10⁻⁶)

sinθ = 0.38

θ = sin⁻¹(0.38)

θ = 22.33 ⁰

<h3>For longest wavelength (λ = 760 nm)</h3>

sinθ = (1 x 760 x 10⁻⁹)/(1 x 10⁻⁶)

sinθ = 0.76

θ = sin⁻¹(0.76)

θ = 49.46 ⁰
