2.seseorang mendorong sebuah meja bermassa 10 kg di atas lantai datar. Koefisien gesek statis antara peti dan lantai adalah 0,5 dan percepatan gravitasi g= 10 m/s²
Answer (4)
It takes 10 dimes to make a dollar so multiply 10 x 8 that will = 80. It also takes 7 dimes to make .70 cents so the answer is is 87 dimes to make $8.70
Both approaches yield the same result, so there are 87 dimes in $8.70.
To determine the number of dimes in $8.70, we can use two different approaches:
Approach 1: Division
1 dime = $0.10
To find the number of dimes, divide the total amount by the value of one dime:
Number of dimes = $8.70 / $0.10
Number of dimes = 87 dimes
Approach 2: Counting by 10 cent
$8.70 is equivalent to 870 cents (since 1 dollar = 100 cents).
Since each dime is worth 10 cents, we can find the number of dimes by dividing the total cents by 10:
Number of dimes = 870 cents / 10 cents
Number of dimes = 87 dimes
Both approaches yield the same result, so there are 87 dimes in $8.70.

To determine the number of dimes in $8.70, you can divide the total amount by the value of a dime, which gives you 87 dimes. Alternatively, convert the total amount to cents and then divide by 10 cents per dime, which also results in 87 dimes. Both methods confirm that there are 87 dimes in $8.70.

*$\boxed{50}$*Solution:*1. Gaya normal ($N$) pada meja adalah berat meja itu sendiri, karena meja berada di atas lantai datar.$N = m \times g = 10 \, \text{kg} \times 10 \, \text{m/s}^2 = 100 \, \text{N}$2. Gaya gesek statis maksimum ($f_{s,max}$) dapat dihitung menggunakan rumus:$f_{s,max} = \mu_s \times N = 0,5 \times 100 \, \text{N} = 50 \, \text{N}$Jadi, gaya gesek statis maksimum yang bekerja pada meja adalah 50 N.*TL;DR:* Gaya gesek statis maksimum yang bekerja pada meja adalah 50 N, yang dihitung menggunakan rumus $f_{s,max} = \mu_s \times N$.
