Answer 1

Answer #1

We know that the average tangential acceleration is

a_avg=(v2-v1)/(t2-t1)

That is

a_avg=(9.6-4.0)/(8-3.44) m/s2

a_avg=5.6/4.56 m/s2

a_avg=1.228. m/s2

One simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line

One simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 10.8 m/s in 2.54 s, what will be his total time?
