All of the above, work is a measurement of energy transfer, in Joules.
Potential energy = Joules
Kinetic energy = Joules
The key thing here is that anything having to do with just energy or energy transfer is measured in joules.

Our team is having a really hard time trying to decode the gibberish
in the question, but they do seem to be picking up a message that
you're in an exam. If that's true, then thank you for taking some of
your precious exam time to greet your many friends on Brainly.
Now turn off your phone and drag your attention back to the exam.
Given that,
Height =1.5 m
Angle = 45°
We need to find the greater speed of the ball
Using conservation of energy
Here, initial velocity and final potential energy is zero.
Put the value into the formula
Hence, the greater speed of the ball is 5.42 m/s.
