1. A spring with a constant of 80 N/m, is extended by 2 m. How much energy stored in the extended spring?
Energi Potensial pegas
Diketahui:
k = konstanta pegas = 80 N/m Δx = perpanjangan pegas = 2 mDitanya:
Ep = energi potensial pegas ? JawabanEp = ½ × k × Î”x²
Ep = ½ × 80 × 2²
Ep = 40 × 4
Ep = 160 J ✔
2. When a 14.0 kg mass hangs from a spring that has a spring constant of 550 N/m, the spring has a length of 82 cm. Determine the length of the spring before any force is applied to it.
Penjelasan:
given :
m = 14.0kg
k = 550N/m
g= 10 m/s²
total length = 82cm = 0,82m
find:
the length of the spring before any force is applied to it, Lo =?
solutions:
F = m. g = 14.0 × 10 = 140N
F = k. ∆x
140 = 550.(0,82 -Lo)
14 = 55(0,82 -Lo)
14 = 45.1 - 55Lo
55Lo = 45.1 -14
= 31.1
Lo = 31.1/ 55
= 0.565m
= 56.5cm

7. The original length of a spring is 8 cm. When a mass is attached to it, the length of the spring is 10.5 cm. Find the percentage increase in the length of the spring.
Jawab:
Penjelasan dengan langkah-langkah:
increase in length :
10.5 - 8 = 2.5cm
% increase :
= increase in length / original value x 100%
=2.5 / 8 x 100
=31.25 %

10. What is the force constant of a spring which is stretcheda) 2 mm by a force of 4N,b) 4cm by a mass of 200g?.
Jawaban:
Untuk menghitung konstanta gaya suatu pegas, kita perlu menggunakan rumus:
k = F / x
Di mana:
k = konstanta gaya (dalam newton/meter)
F = gaya yang diberikan pada pegas (dalam newton)
x = perpanjangan pegas (dalam meter)
a) Dalam hal ini, gaya F = 4 N, dan perpanjangan pegas x = 2 mm = 2 x 10^-3 m. Jadi, konstanta gaya k = F / x = (4 N) / (2 x 10^-3 m) = 2000 N/m.
b) Dalam hal ini, massa m = 200 g = 0.2 kg. Selain itu, kita juga tahu bahwa gaya gravitasi pada bumi adalah F = m x g, di mana g adalah percepatan gravitasi (9.8 m/s^2). Jadi, gaya F = 0.2 kg x 9.8 m/s^2 = 1.96 N. Perpanjangan pegas x = 4 cm = 4 x 10^-2 m. Jadi, konstanta gaya k = F / x = (1.96 N) / (4 x 10^-2 m) = 49 N/m.

15. A box having a mass of 1.5 kg is accelerated across a table at 1.5 m/s2. the coefficient of friction on the box is 0.3. what is the force being applied to the box? if this force were applied by a spring, what would the spring constant have to be in order for the spring to be stretched to only 0.08 m while pulling the box?
Jawaban:
28.125 N/m
Penjelasan:
Untuk menghitung gaya yang diterapkan pada kotak, kita dapat menggunakan persamaan gaya = massa x akselerasi. Jadi, gaya yang diterapkan pada kotak adalah:
F = 1.5 kg x 1.5 m/s2 = 2.25 N
Untuk menghitung konstanta pegas yang diperlukan untuk menarik kotak sejauh 0,08 m, kita dapat menggunakan persamaan pegas: F = k x d (dimana F adalah gaya, k adalah konstanta pegas, dan d adalah jarak). Karena gaya yang diberikan adalah 2,25 N dan jarak adalah 0,08 m, konstanta pegas yang diperlukan adalah:
k = F / d = 2.25 N / 0.08 m = 28.125 N/m

17. If a 10 N/m spring is stretched 0.3 m from its rest position, what is the potential energy stored in the spring?
JAWABAN:
Diketahui :
Diketahui :k = 10 N/m
Diketahui :k = 10 N/mΔx = 0,3 m
Diketahui :k = 10 N/mΔx = 0,3 mDitanya :
Diketahui :k = 10 N/mΔx = 0,3 mDitanya :EP = ?
Diketahui :k = 10 N/mΔx = 0,3 mDitanya :EP = ?Jawab :
Diketahui :k = 10 N/mΔx = 0,3 mDitanya :EP = ?Jawab :EP = 1/2. k. Δx^2
EP = 1/2. 10. 0,3^2
EP = 1/2. 10. 0,3^2EP = 1/2. 10. 0,09
EP = 1/2. 10. 0,3^2EP = 1/2. 10. 0,09EP = 0,45 J
EP = 1/2. 10. 0,3^2EP = 1/2. 10. 0,09EP = 0,45 JJadi, energi potensial yang tersimpan pada pegas adalah 0,45 J (D).
