## At what point in its trajectory does a projectile have minimum speed?

At the highest point of the trajectory of a projectile, its speed is minimum. This is because the horizontal speed of the projectile remains constant. Now, the only force acting on the projectile is gravity, and the acceleration is that due to gravity, so its speed is minimum at the highest point of the trajectory.

## At what time does the object have its minimum velocity?

Test each solution to determine whether it is a maximum or a minimum. Choose a point just to the left of the extremum and another point just to the right. If acceleration is negative to the left and positive to the right, the point is a minimum velocity.

## What is the speed of the projectile when it is at the highest point in its trajectory?

At a projectile’s highest point, its velocity is zero. At a projectile’s highest point, its acceleration is zero.

## At what point’s on its trajectory is the acceleration zero?

Question: At what point(s) on its trajectory is the acceleration zero? At the lowest point on its trajectory. Immediately after contact with the bat. The acceleration is never zero.

## At what points the projectile has maximum and minimum velocities?

Answer: In a Trajectory the projectile would have Minimum velocity at Trajectory point ( At the maximum height ). & Possess Maximum velocity at initial projection point (due to initial acceleration) & at the point when projectile hits the ground.

## When velocity is maximum What is acceleration?

At the equilibrium position, the velocity is at its maximum and the acceleration (a) has fallen to zero.

## What is the minimum velocity when acceleration is zero?

In part (b), instantaneous acceleration at the minimum velocity is shown, which is also zero, since the slope of the curve is zero there, too. Thus, for a given velocity function, the zeros of the acceleration function give either the minimum or the maximum velocity.

## What is the minimum velocity?

Minimum and maximum speed: For a continuous velocity function, the minimum speed is zero whenever the maximum and minimum velocities are of opposite signs or when one of them is zero.

## How long will the ball travel before it reaches the ground?

The ball will travel about 1.1 meters before hitting the ground.

## What do you call the trajectory of a projectile in free fall?

The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning of the trajectory, after which the only interference is from gravity. One of the key components of projectile motion and the trajectory that it follows is the initial launch angle.

## What is the acceleration of the ball just before it hits the ground?

Conclusion: The magnitude of the velocity of the ball is 26.3 m/s for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward.

## What is acceleration at the top of trajectory?

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.

## Is vertical acceleration ever zero?

Because there is no air resistance, no net horizontal force acts on the human cannonball. Thus, the horizontal velocity is constant. Is the vertical component of velocity ever zero? Both accelerations are equal to zero.

## How do you find acceleration at the highest point?

By applying the equation v=u+at (v is final velocity, u is initial velocity, a is acceleration and t is time) here and taking ag=−9.8m/s2 (at this point acceleration due to gravity is in opposite direction of motion) we see that the value of v slowly decreases with time.
