A moving object has a kinetic energy of 138 J

and a momentum of 23.9 kg·m/s.
a) Find the speed of the object.
Answer in units of m/s.

To find the speed of the object, we can use the relationship between kinetic energy and momentum. The kinetic energy of an object can be calculated using the equation:

Kinetic Energy (KE) = 0.5 * mass * velocity^2.

Here, we are given the kinetic energy (KE) as 138 J and momentum as 23.9 kg·m/s.

We know that momentum (p) can be calculated as:

Momentum (p) = mass * velocity.

So, rearranging the equation, we get:

velocity = momentum / mass.

To find the velocity (speed), we need to divide the given momentum by the mass of the object.

However, the mass of the object is not provided in the question. Without the mass, we cannot determine the speed of the object.
