If a 50kg cheeetah had kinetic energy of 18,000 joules , how fast is the cheetah running?
Well, let's hope that the cheetah didn't spend all that energy chasing after a laser pointer! But to answer your question, we can use the formula for kinetic energy (KE = 1/2 * m * v^2) to solve for velocity (v).
Given that the mass (m) of the cheetah is 50 kg and the kinetic energy (KE) is 18,000 joules, we can rearrange the formula:
KE = 1/2 * m * v^2
18,000 = 1/2 * 50 * v^2
Now, let's do some math magic:
36,000 = 50 * v^2
Divide both sides by 50:
720 = v^2
Take the square root of both sides:
v ≈ √720
v ≈ 26.87 m/s (rounded to two decimal places)
So, it seems like our speedy friend is running at approximately 26.87 meters per second! Just try to keep up with that, Road Runner!
To determine the speed of the cheetah, we can use the equation for kinetic energy:
Kinetic energy = (1/2) * mass * velocity^2
Rearranging the equation, we can solve for velocity:
velocity^2 = (2 * kinetic energy) / mass
Substituting the given values:
velocity^2 = (2 * 18000 joules) / 50 kg
velocity^2 = 360 joules / kg
Taking the square root of both sides:
velocity = √(360 joules / kg)
Calculating the square root:
velocity ≈ √360 ≈ 18.97 m/s
Therefore, the cheetah is running approximately 18.97 meters per second.
To determine the speed of the cheetah, we need to use the formula for kinetic energy:
KE = (1/2)mv^2
Where:
KE = Kinetic energy
m = Mass of the object (cheetah in this case)
v = Velocity (speed) of the object (cheetah in this case)
Given:
Mass of the cheetah (m) = 50 kg
Kinetic energy (KE) = 18,000 joules
Rearranging the formula, we can solve for the velocity of the cheetah:
v = √(2KE/m)
Plugging the given values into the formula, we have:
v = √(2 * 18,000 J / 50 kg)
Now, let's calculate the velocity of the cheetah.
Calculating the square root:
v = √(360 J/kg)
v ≈ 18.97 m/s
Therefore, the cheetah is running at a speed of approximately 18.97 meters per second.
KE = 1/2 M V^2
18000 = 1/2 (50) v^2
18000 = 25v^2
18000/25 = 25v^2/25
720 = v^2
720 (sqrt) = v^2
