Q.1 A wheel starts from rest and rotates with constant angu- lar acceleration to reach an angular speed of 12.0 rad/s in
3.00 s. Find (a) the magnitude of the angular acceleration
of the wheel and (b) the angle in radians through which it
rotates in this time interval.

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
