At a projectile's highest point, its velocity is zero. At a projectile's highest point, its acceleration is zero.
2.)If the velocity of the ball thrown upward at that elevation is 80 m/s, then its velocity going downward in that the same elevation is the same ( 80 m/s).
3.)zero
At a projectile's highest point, its acceleration is zero.
4.)So the acceleration of the projectile is equal to the acceleration due to gravity, 9.81 meters/second/second, from just after its thrown, through its highest point, and until just before it hits the ground.
5.)So after one second, the acceleration of the ball is 9.8 m/s² and its velocity is 9.8 m/s. When you throw the ball upward, that acceleration is still 9.8 m/s².
At a projectile's highest point, its velocity is zero.
2.This happens because regardless of mass, the acceleration due to gravity is constant at 9.81 meters per second per second (9.81 m/s^2) or 32 feet per second per second (32 ft/s^2). As a result, for every second an object experiences free fall, gravity will accelerate it so its velocity increases 9.81 m/s or 32 ft/s.
3.Zero
At a projectile's highest point, its acceleration is zero.
4.So the acceleration of the projectile is equal to the acceleration due to gravity, 9.81 meters/second/second, from just after its thrown, through its highest point, and until just before it hits the ground.
5.C.9.8 m/s².
So after one second, the acceleration of the ball is 9.8 m/s² and its velocity is 9.8 m/s. When you throw the ball upward, that acceleration is still 9.8 m/s².
