An object has a KE= 18000 and a massof 98kg what is the speed of the object
18000 what
To find the speed of the object, we can use the formula for kinetic energy (KE):
KE = 1/2 * m * v^2
where KE is the kinetic energy, m is the mass of the object, and v is the speed.
Given that the kinetic energy (KE) is 18000 J and the mass (m) is 98 kg, we can rearrange the formula to solve for v:
18000 = 1/2 * 98 * v^2
Next, we can simplify the equation:
18000 = 49 * v^2
Now, divide both sides of the equation by 49:
18000 / 49 = v^2
Simplifying the left side of the equation:
367.35 = v^2
Finally, take the square root of both sides to find the speed (v):
v = √367.35
Using a calculator, we find that the speed of the object is approximately 19.17 m/s (rounded to two decimal places).
