The maximum possible force of static friction between two surfaces is given by:
F = μN
F = max friction force, μ = coefficient of static friction, N = normal force
The normal force N equals the object's weight:
N = mg
m = mass, g = gravitational acceleration
Make a substitution:
F = μmg
Given values:
F = 500N, m = 100kg, g = 9.8m/s²
Plug in and solve for μ:
500 = μ(100)(9.8)
μ = 0.51
349.6/6.2= 56.38709677419355 Rounded it would be 56, so the car travels about 56 miles per hour
Answer:
190v I believe
hope this helped a little and if it did pls mark brainiest :)
Answer:
800 J/kg/C
Explanation:
Specific Heat Capacity can be calculated using the formula:
c = Q/mT
Where c is the specific heat capacity in <em>J</em><em>/</em><em>K</em><em>g</em><em>/</em><em>C</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>Q is the amount of energy supplied in <em>J</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>m is the mass of object in <em>k</em><em>g</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>T is the <em>c</em><em>h</em><em>a</em><em>n</em><em>g</em><em>e</em><em> </em>in Temperature in <em>C</em><em>.</em>
Hence by applying this formula, we get:
c = (1.6 × 10^5)/(10)(34 - 14)
c = <u>8</u><u>0</u><u>0</u><u> </u><u>J</u><u>/</u><u>k</u><u>g</u><u>/</u><u>C</u>
