an object is thrown upwards with initial velocity of 25m/s and the time it took to hit the ground is 5 seconds then find the height obtained. (Take acceleration due to gravity as 10m/s²) (use the kinematical equation S=ut+1/2at²)

Step-by-step explanation:

Kinematics is a subfield of physics, developed in classical mechanics, that describes the motion of points, bodies, and systems of bodies without considering the forces that cause them to move The kinematic equations are a set of equations that describe the motion of an object with constant acceleration. Kinematics equations require knowledge of derivatives, rate of change, and integrals. To keep our focus on high school physics, we will not be covering integrals. Kinematics aims to provide a description of the spatial position of bodies or systems of material particles, the rate at which the particles are moving (velocity), and the rate at which their velocity is changing (acceleration). Kinematic variables allow the description of the motion of a body without reference to variables that act to change the motion of the body. (The variables that act to change the motion of a body, kinetic variables, will be covered elsewhere.) Kinematics involves position, velocity and acceleration (and their rotational equivalents). Position is the point in space that an object occupies, this needs to be defined in some coordinate system. Velocity is the rate of change of position with respect to time.
