What is potential energy ​

it is a type of energy with the formula of u=mgh

Explanation:

m means mass

g means gravitational field and

h means height

answer; ///i believe that the correct answer is (45*) at a 45 degree check first good

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
