Determine his maximum speed vmax

Reference no: EM13678782

A sprinter running straight reaches his maximum speed v_max in 2 seconds from rest with constant acceleration. He then maintains that speed until he looks back to see that the other sprinters in the race are far behind. At this moment, he starts showboating and slowing down at a constant rate until he reaches the finish line at a velocity of 2 m/s. If the slowing down portion of his race takes 1 second and he finishes the race of 100 m in a total of 9.6 seconds, determine his maximum speed v_max .

Documentaries as a huge sphere with earth in the middle : Where exactly does CMB come from? I've seen it in documentaries as a huge sphere with Earth in the middle. But if all this radiation was ejected from the start of the universe some time after the big bang; why can we see it? Certainly the radiation m..

How much later does it hit the bottom of the cliff : A stone is thrown vertically upward by a speed of 17.8 m/s from the edge of a cliff 75.0 m high. What is its speed just before hitting? What total distance did it travel?

Decide the initial and final velocities of the particle : The acceleration of a particle moving along a horizontal path is constant and equal to 4ft/sec^2 to the left. Through a certain time internal, the particle has a displacement of 54ft to the right and travels a total distance of 90ft.

Determine what is his speed as he crosses the finish line : A sprinter can accelerate with constant acceleration for 3.40s before reaching top speed. He can run the 100-meter dash in 10 s. Determine what is his speed as he crosses the finish line?

Determine his maximum speed vmax : A sprinter running straight reaches his maximum speed vmax in 2 seconds from rest with constant acceleration. He then maintains that speed until he looks back to see that the other sprinters in the race are far behind.

What is the potential dissimilarity among the plates : A point charge q = 2.5 nC is initially at rest adjacent to the negative plate of a capacitor. The charge per unit area on the plates is 4.5 µC/m 2 and the space among the plates is 6.0 mm. What is the potential dissimilarity among the plates?

What is the capacitance of this capacitor : A capacitor can be made from two sheets of aluminium foil separated by a sheet of waxed paper. If the sheets of aluminium are 0.37 m by 0.33 m and the waxed paper, of slightly larger dimensions, is of thickness 0.040 mm and dielectric constant? = 2.5..

Which can not be explained by first quantized string theory : In the strong coupling limit of kind IIA and heterotic E8 string theory, we get 11 dimensional M-theory in which we have no strings. Instead, we have M2 brines. Are there any other backgrounds in string theory which can't be explained by first quanti..

Consistent by what is typical of static electricity : Common transparent tape becomes charged when pulled from a dispenser. If one piece is placed above another, the repulsive force can be great enough to support the top piece's weight.
