He decides to test the car by racing with another speedster, john. both start from rest,
but experienced john leaves the starting line 1.00 s before peter. if john moves with a
constant acceleration of 3.50 m/s2, and peter maintains an acceleration of 4.90 m/s2,
find (a) the time it takes peter to overtake john, (b) the distance peter travels before he
catches john, and (c) the speeds of both cars at the instant peter overtakes john.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Answer (d) the universe had cooled enough for atoms to combine, protons and neutrons were too far apart to form nuclei;

Answerthe global climate during the paleogene departed from the hot and humid conditions of the late mesozoic era and began a cooling and drying trend which dispite having been periodically disrupted by warm periods such as the paleocene-eocene thermal maximum, persists today;
