One way to approach this is to use Phil’s average speed to find how far he has run duringthe time it takes for Mala to finish the race.From vdd v t100.0 m(12.8 s) 94.1 m. Since Phil has onlyt Phil Phil Mala13.6 straveled 94.1 m when Mala crosses the finish line, he is behind by100 m 94.1 m 5.9 m 6 m.600h3-60. The time for Terrence to land from his maximum height is the same as the time ittakes for him to rise to his maximum height. Let’s consider the time for him to land froma height of 0.6 m.
