A student designs a new amusement park ride that involves a type of bumper car that has a spring on the front to cushion collisions. To test the bumper, the student attaches one spring to the front of a single car. In a collision, car 1 with total mass 440 kg is moving at 3.0 m/s [E] toward car 2 with total mass 4.0 x102 kg moving at 3.3 m/s [W]. During the collision, the spring compresses a maximum of 44 cm. Determine the spring constant.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
