A 65 kg sprinter completes a 100 m race in 9.83 s. Calculate the average kinetic energy of the sprinter.

V = 100m/9.83s. = 10.17 m/s.


KE = 0.5*M*V^2 = 0.5*65*10.17^2=3361 J.

Well, let's sprint into this question, shall we?

To calculate the average kinetic energy of our speedy sprinter, we need to use the equation for kinetic energy:

Kinetic Energy = (1/2) * mass * velocity^2

First, let's find the velocity of the sprinter. Given that the sprinter completes the 100m race in 9.83s, we can calculate the velocity using the formula:

Velocity = distance / time

Distance = 100m
Time = 9.83s

Velocity = 100m / 9.83s ≈ 10.17 m/s

Now we have the velocity, let's plug in the values:

Kinetic Energy = (1/2) * mass * velocity^2

Mass = 65 kg
Velocity = 10.17 m/s

Kinetic Energy = (1/2) * 65 kg * (10.17 m/s)^2

And ... calculating ...

Kinetic Energy ≈ 3302 Joules

So, the average kinetic energy of our sprightly sprinter is approximately 3302 Joules. Keep those feet flying!

To calculate the average kinetic energy of the sprinter, we will use the formula for kinetic energy:

Kinetic Energy = 1/2 * mass * velocity^2

First, let's calculate the velocity of the sprinter. We know that the distance covered is 100 m and the time taken is 9.83 s.
So, velocity = distance / time = 100 m / 9.83 s ≈ 10.17 m/s.

Now, we can substitute the values into the kinetic energy formula:
Kinetic Energy = 1/2 * mass * velocity^2
= 1/2 * 65 kg * (10.17 m/s)^2
≈ 3307.19 Joules

Therefore, the average kinetic energy of the sprinter is approximately 3307.19 Joules.

To calculate the average kinetic energy of the sprinter, we need to use the formula for kinetic energy:

Kinetic Energy = (1/2) * mass * velocity^2

First, we need to determine the velocity of the sprinter. We can use the formula for average speed:

Average Speed = Distance / Time

The distance covered by the sprinter is given as 100 m, and the time taken is given as 9.83 s. Plugging these values into the formula, we can calculate the average speed.

Average Speed = 100 m / 9.83 s = 10.18 m/s (rounded to 2 decimal places)

Now that we have the average speed, we can calculate the kinetic energy of the sprinter using the formula mentioned earlier.

Kinetic Energy = (1/2) * mass * velocity^2

Given that the mass of the sprinter is 65 kg and the average speed is 10.18 m/s, we can substitute these values into the formula to find the kinetic energy.

Kinetic Energy = (1/2) * 65 kg * (10.18 m/s)^2

Calculating this expression, we find:

Kinetic Energy ≈ 3326.28 Joules (rounded to 2 decimal places)

Therefore, the average kinetic energy of the sprinter is approximately 3326.28 Joules.
