What is kinematics?
explain briefly ~

hlo

Kinematics is a branch of physics (or physical science) that deals with aspects of motion apart from considerations of mass and force

Explanation:

So as an example - describing the motion of a racecar moving on a track or an apple falling from a tree, but only in terms of the object's position, velocity, acceleration, and time.

mm and hola

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

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
