A world class sprinter can burst out of the blocks to essentially top speed of about 11.5 ms in the first 15m of the racewhta is the average acceleration of the sprinter?

The average acceleration of the sprinter can be calculated using the formula ( a = \frac{v_f - v_i}{t} ), where ( v_f = 11.5 , \text{m/s} ), ( v_i = 0 , \text{m/s} ), and ( t = 15 , \text{m} ). Substituting these values into the formula gives an average acceleration of approximately 0.77 m/s².


If a sprinter has a mass of 80 kg and a kinetic energy of 3000 what is the speed?

Although the units of the kinetic energy aren't given, we have to assume that the "3,000"are joules ... the SI unit of energy; otherwise we can't go anywhere at all with this question.K.E. = 1/2 m V2 = 3,000 joulesm V2 = 6,00080 V2 = 6,000V2 = 6,000/80 = 75V = sqrt(75) = 8.66 meters per second (rounded)


What happens to your body when you play sports?

So imagine that you start running. Here's what happens: * The muscle cells burn off the ATP they have floating around in about 3 seconds. * The phosphagen system kicks in and supplies energy for 8 to 10 seconds. This would be the major energy system used by the muscles of a 100-meter sprinter or weight lifter, where rapid acceleration, short-duration exercise occurs. * If exercise continues longer, then the glycogen-lactic acid system kicks in. This would be true for short-distance exercises such as a 200- or 400-meter dash or 100-meter swim. * Finally, if exercise continues, then aerobic respiration takes over. This would occur in endurance events such as an 800-meter dash, marathon run, rowing, cross-country skiing and distance skating.


A sprinter can accelerate with constant acceleration for 3.40 s before reaching top speed He can run the 100-meter dash in 10 s?

1/2a(3.4)^2+[3.4a(a=0)](6.6)=100 [] is Vi and a in this case is 0 at it stops to accelerate when it gets to 3.4s so a=100/(.5)(3.4)^2....=17.30 now Vf=(3.4*17.30)+17.30(6.6)...=173.01


What distance would you cover with one long step?

Twice the length of half a big step. There is no answer for this, as a big step for a baby might be 10cm, but for an adult male sprinter could be 10m, or for a cheetah could be as much as 30m.
