The kinetic energy of the athlete can be calculated using the formula KE = 0.5 * m * v^2, where m = mass of the athlete (75 kg) and v = speed. Since the athlete is running at a constant speed over 100m in 10 seconds, we can calculate the speed using distance/time. The speed is 10 m/s. Plugging these values into the formula, the kinetic energy of the athlete is 3750 Joules.
The Planck constant has dimensions of energy multiplied by time. It is typically expressed in units of Joule seconds (J⋅s) or electron volt seconds (eV⋅s).
The average constant speed of the object between 2 and 5 seconds is the total distance covered divided by the time elapsed. If you have the distance covered during this time interval, divide it by 3 seconds (5s - 2s) to get the average constant speed.
The inertia constant of a generator is a measure of how much kinetic energy it can provide to the power system during sudden changes in frequency. It is typically expressed in seconds and is a key parameter for determining the system's ability to maintain stability during disturbances. Generators with higher inertia constants can better withstand sudden changes in power demand or system disturbances.
No, the motion of the seconds hand of a watch is not an example of uniform velocity. The seconds hand moves in a circular motion at a constant speed, rather than moving in a straight line at a constant velocity. Uniform velocity refers to motion in a straight line with a constant speed.
If the graph is traveling at a constant speed of 1 unit per minute, then after 5 seconds it would have traveled 5/60 = 1/12 units. Therefore, the speed at 5 seconds is 1/12 units per second.

Don't let them confuse you. Kinetic energy is 1/2 mv2. His time of acceleration and the force acting on him are irrelevent. k = mv2/2 k = 100kg * (12m/s)2/2 =14400 kgm2/s2/2 =7200kgm2/s2 k = 7200N
His speed is 11.25 miles per hour.
