## When a ball is thrown upward its initial velocity is?

A ball is thrown upward with an initial velocity V0 from the surface of the earth. The motion of the ball is affected by a drag force equal to mγv2 (where m is mass of the ball, v is its instantaneous velocity and v is a constant).

## When something is thrown up what is its velocity at the highest point?

zero

At a projectile’s highest point, its velocity is zero. At a projectile’s highest point, its acceleration is zero. The rate of change of the \begin{align*}x\end{align*} position is changing with time along the projectile path.

**When a ball is thrown vertically upwards with velocity v?**

When a ball is thrown vertically upwards with velocity v0, it reaches a maximum height of h. If one wishes to triple the maximum height then the ball should be thrown with velocity.

### What happens to the acceleration of a ball after it is thrown upward into the air neglect air resistance?

The ball’s acceleration is the same throughout the throw (It is 9.8 m/s2 toward the earth). The direction of the ball’s motion is upward, and doesn’t change. As you throw the ball up into the air, its direction is up, but the speed decreases due to the pull of gravity.

### What is the final velocity when a ball is thrown upward?

The height where the velocity becomes zero which is the maximum height the ball went upward, say is H. And for this upward movement, the final velocity v2 is 0 because the ball has stopped at the end of this upward traversal. Why an object thrown upwards comes down after reaching a point?

**What is the speed of the ball when it hits the ground?**

Since the (vertical) velocity of the ball is given by (assuming g ≈ constant) v(t) = ds dt = v0 − gt, the speed of the object when hits the ground is the velocity at time t ∗, where t ∗ is the value of t when s(t) = sG = 0 (if your reference system is placed at s = sG = 0 for the ground).

#### What happens to the vertical velocity as an object rises?

(c) The velocity in the vertical direction begins to decrease as the object rises; at its highest point, the vertical velocity is zero. As the object falls towards the Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity.

#### What is the initial velocity of a shell shot into the air?

(d) The x and y motions are recombined to give the total velocity at any given point on the trajectory. During a fireworks display, a shell is shot into the air with an initial speed of 70.0 m/s at an angle of above the horizontal, as illustrated in (Figure).
