The speed or velocity of the ball when it reaches its maximum height will be equal to 0
Ball motion is a motion by particles that move along a curved path and are affected by gravity
Ball motion is a movement with the direction of the throw / kick up which forms an elevation angle to the y axis or x axis in a 2 dimensional plane. Ball motion can be likened to projectile motion.
There are two motions experienced by the ball in this motion, namely horizontal motion and vertical motion
Horizontal motion is called constant velocity motion with constant velocity and vertical motion is called uniformly accelerated motion with constant acceleration (a = g)
Velocity itself is a vector, has a direction and a magnitude, while speed is a scalar, has only a magnitude.
The initial velocity of the ball equal to vo in the y axis direction will continue to decrease because it is slowed by the gravity of the earth so that the speed of the ball will be equal to zero. When this ball speed (vy = 0), the ball reaches a maximum height and at that time the right ball will start to reverse toward the ground again.
• Time to reach the maximum height (h):
vy = vo sin teta - gt
0 = vo sin but -gt
[tex]\displaystyle t_ {h_max} = {\frac {v_ {0} \sin (\theta)} {g}}}[/tex]
• The maximum height of ball
[tex]\displaystyle h_{max}= {\dfrac {v_ {0} ^ {2} \ sin ^ {2} (\theta)} {2g}}[/tex]
