How fast is a projectile moving at the top of its trajectory?
At the top of its trajectory, a projectile's vertical velocity is momentarily zero, while its horizontal velocity remains constant. The speed of a projectile at the top of its trajectory can be determined by calculating the magnitude of its velocity vector using the horizontal and vertical components of velocity.
Find average acceleration and instanious acceleration?
average acceleration is the average of the acceleration of a body in its entire motion where as instantaneous acceleration is the rate of change of velocity at an instant. it may be a function of time or velocity or displacement.
Can speed and velocity be the same?
No, speed and velocity are not the same. Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction of motion. Therefore, two objects can have the same speed but different velocities if they are moving in different directions.
When is instantaneous acceleration and average acceleration the same?
Instantaneous acceleration and average acceleration are the same when an object's acceleration is constant over the entire time interval being considered. This means that the object's velocity is changing at a constant rate, resulting in both the instantaneous and average accelerations being equal.
Can a particle with maximum speed have zero acceleration?
Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.Yes.

What effect does changing the initial position have on velocity time graph?
Changing the initial position on a velocity-time graph does not affect the velocity itself, as the graph represents how velocity changes over time rather than position. The initial position can shift the entire graph vertically, but this does not alter the slope or the overall shape of the graph. Thus, while the position at a specific time may change, the relationship between velocity and time remains intact.

Is it possible for the average velocity of an object to be zero during some interval even thought its average velocity for the first half of the interval is not zero reexplain and cite an example?
Yes, it is possible for the average velocity of an object to be zero during a given interval even if its average velocity for the first half of the interval is not zero. This can occur when the object moves in opposite directions such that the distances traveled cancel out over the entire interval. For example, if an object moves 3 meters to the right and then 3 meters to the left in equal times, its average velocity for the entire interval would be zero.

I was changing out a bad CPU fan in a laptop do you need to add thermal compound when changing?
If you're just changing the fan, no. If you're changing the entire heatsink, yes.
Is it possible for the average velocity of an object to be zero during some interval even thought its average velocity for the first half of the interval is not zero explain and cite an example?
Yes, it is possible for the average velocity of an object to be zero during some interval, even if its average velocity for the first half of the interval is not zero. This can occur if the object moves in opposite directions with equal distances during the two halves of the interval. For example, if a car moves 3 miles east in the first half of an hour and then moves 3 miles west in the second half of an hour, its average velocity for the entire hour would be zero.

What was her average velocity for the entire trip?
To calculate average velocity, you would divide the total displacement by the total time taken. If you have those values, you can plug them into the formula to find the average velocity for the entire trip.
What happens during a total solar eclipse?
The entire area becomes completely dark as a normal solar eclipse woulddo to a certain area.
What is the acceleration if the velocity is 0?
It's not possible to tell from only that much information. When you throw a rock up, its acceleration is the acceleration of gravity from the moment it leaves your hand until it hits the ground. But its velocity is upward some time, downward some time, and zero at the top.
