In the 1991 world track and field championships in tokyo, mike powell jumped 8.95 m, breaking by a full 5 cm the 23-year long-jump record set by bob beamon . assume that powell's speed on takeoff was 9.5 m/s (about equal to that of a sprinter) and that g = 9.80 m/s2 in tokyo. how much less was powell's horizontal range than the maximum possible horizontal range for a particle launched at the same speed?

0.26 m

Explanation:

θ = Angle at which the jumper launched

g = Acceleration due to gravity = 9.8 m/s²

R = Range = 8.95 m

v = Velocity of the jumper = 9.5 m/s

Range of projectile

When, θ = 45° maximum range is obtained

sin(2×45) = sin90 = 1

Maximum range

So, Mike Powell jumped 9.21-8.95 = 0.26 m less than the maximum range if launched at the same speed.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
