HI I am stuck on how they work this one problem S= 4m how fast was the car travling to have skid maks of 121 feet can someone help me please
Of course, I can help you with that problem! The formula you provided, S = 4m, relates the distance of skid marks (S) to the speed of the car (m). To find the speed of the car, we need to rearrange the formula to solve for m.
First, divide both sides of the equation by 4 to isolate "m":
S/4 = m
Now let's substitute the given value of S into the equation. You mentioned that the skid marks were 121 feet long, so we replace S with 121:
121/4 = m
To find the value of m, simply divide 121 by 4:
m ≈ 30.25
Therefore, the car was traveling at approximately 30.25 units of speed. Note that the units of speed are not specified, so it's unclear whether it should be measured in miles per hour, meters per second, or some other unit.
