A steel ball is traveling through water with a speed of x meters per second, where x is positive. The drag force, F, in newtons (N) is:F=0.5+0.004(x+50)(x−2At what speed in meters per second does the ball have a force of 0.5N on it?
Q. A steel ball is traveling through water with a speed of x meters per second, where x is positive. The drag force, F, in newtons (N) is:F=0.5+0.004(x+50)(x−2At what speed in meters per second does the ball have a force of 0.5N on it?
Given Equation: We are given the drag force equation F=0.5+0.004(x+50)(x−2) and we need to find the value of x when F=0.5N. First, we set the force F to 0.5N in the equation and solve for x. 0.5=0.5+0.004(x+50)(x−2)
Set Force to 0.5N: Subtract 0.5 from both sides of the equation to isolate the term with x. 0=0.004(x+50)(x−2)
Subtract 0.5: Divide both sides of the equation by 0.004 to simplify the equation.0=(x+50)(x−2)
Divide by 0.004: Now we have a quadratic equation in the form of (x+50)(x−2)=0. We can find the values of x by setting each factor equal to zero.x+50=0 or x−2=0
Quadratic Equation: Solve for x in both equations.x=−50 or x=2
Solve for x: Since x represents a speed and speed cannot be negative, we discard the negative value.Therefore, the speed at which the ball has a force of 0.5N on it is x=2 meters per second.
