When an archer shoots an arrow straight up with an initial velocity magnitude of 100.0 ms. After 5.00 s the velocity is 51.0 ms. At what rate is the arrow decelerated?

This occurred over a period of 5 seconds so
The (negative) acceleration - aka - deceleration is (-49 m/s)/(5 s) = -9.8 m/s²

What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time
If a small marble is dropped straight downward what is the initial velocity of the marble?
The initial velocity is zero. In most basic physics problems like this one the initial velocity will be zero as a rule of thumb: the initial velocity is always zero, unless otherwise stated, or this is what you are solving for Cases where the initial velocity is not zero examples a cannon ball is shot out of a cannon at 50 mph a ball is thrown from at a speed of 15 mph etc
An arrow is shot straight up at an initial velocity of 250ms How long will it take to hit the ground?
This is a velocity question so u need to use uvaxt
Can the effect of initial velocity on final velocity be predicted?
Well, (final velocity) = (initial velocity) + (acceleration x time)
What is the formula for calculating final velocity when you know the initial speed and the acceleration?
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
The horizontal and vertical components of the initial velocity of a tennis ball are 18.2 ms and 21.3 ms respectively what is the magnitude of the initial velocity of the ball?
To take the magnitude of the velocity you will need to square both the horizontal and vertical components and then take the square root of their sum. So: V=(Vx2+Vy2)1/2

Where A Particle Is Projected Along A Linear Plane. The Horizontal Component Of The Velocity Is Twice The Vertical Component What Is The Initial Magnitude Of The Velocity And The Angle At Which It Is?
The initial velocity is sqrt(5) times the vertical component, and its angle relative to the horizontal direction, is 0.46 radians (26.6 degrees).

A rookie quarterback throws a football with an initial upward velocity component of 16.7 and a horizontal velocity component of 20.2 Ignore air resistance?
The initial velocity of the football can be easily found by solving for the magnitude of the vector formed by adding the two components given. This is accomplished using the Pythagorean theorem. The initial velocity of the football is approximately 26.2 m/s.
If the rocket has an initial mass of 6000 and ejects gas at a relative velocity of magnitude 2000 how much gas must it eject in the first second to have an initial acceleration of 25.0?
985kg
Is it true that you find acceleration when initial velocity final velocity and time are given?
With that information, you can find the average magnitudeof the accelerationduring that period of time. You can't tell what either the magnitude or directionwere at any time during, only the average magnitude for the whole interval.

What does initial velocity means?
initial velocity is the velocity with which a particle starts its journey.
