A villain with mass 70.0 kg runs at a velocity of 10.0 m/s into Chuck Norris’ fist moving at a speed of 0.100 m/s. The villain is knocked back at a velocity of 9.44 m/s and angle 20.0° from the horizontal, and Chuck Norris’ fist moves at a velocity of 0.0500 m/s and 10.0° from the horizontal. a. What is the mass of Chuck Norris’ fist in kg? b. How much kinetic energy is lost in the collision?

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.
