Question:

A SUV travelling along a straight road has kinetic energy of 150 kJ. The brakes are applied, and it is brought to rest over a distance of 75 m. What is the average force of the car breaks?

Answer:

First, identify what the question is asking. The question is asking for force of car breaks. Second, identify the right formula. This is a work formula; W=F*s. F= Force of the object and s = displacement of the object. Third, plug in values with units of what you do have. W = 150 kJ and s = 75 m. Fourth, to solve for F it must be isolated by dividing s from both sides. Fifth, F = W / s or F = 150 kJ / 75 M equates to 2 N. To check your work plug in 2N * 75 equals to 150 kJ.

Answer:

The goal is to isolated the variable "h". Set the < sign to equal sign. Divide 4.7 to both sides. 4.7h / 4.7 equals h; 18/4.7 equals The h is now isolated and your answer is h = 3.829 Check the problem and see were to round answer to. States round to the nearest hundredths. Final answer is 3.83
