Use the table to answer the questions. what is the fastest time trial for the first quarter checkpoint? what is the slowest time trial for the first quarter checkpoint? what is the range of times measured for this checkpoint? all answers in seconds

The fastest time trial is the one that takes the fewest seconds.

∴ The fastest time trial is Trial #3 (2.02 s).

The slowest time trial is Trial #1 (2.15 s).

The range of times is the difference between the largest and smallest measurements.

Range = 2.15 s – 2.02 s = 0.13 s

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
