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.
If an archer shoots an arrow straight up with an initial velocity magnitude of 100.0 ms After 5.00 seconds the velocity is 51.0 ms. At what rate is the arrow decelerated?
The average deceleration of the arrow can be calculated using the formula: average deceleration = (final velocity - initial velocity) / time. Plugging in the values gives an average deceleration of (51.0 - 100.0) / 5.00 = -9.8 m/s^2. This negative value indicates that the arrow is decelerating due to the acceleration of gravity.
What is magnitude of their initial momentum?
The magnitude of their initial momentum depends on the mass and velocity of the objects in question. It is calculated as the product of mass and velocity.
What is the range of change of velocity?
The range of change of velocity is determined by the final velocity minus the initial velocity. It represents the magnitude and direction of the change in velocity of an object.
What is the magnitude of their initial momentum?
The magnitude of their initial momentum is the sum of the magnitudes of their individual momenta. It is calculated by multiplying the mass of each object by its velocity and then summing these values for all objects involved.
What is the magnitude of the vertical component of the velocity of the plane in item 1?
The magnitude of the vertical component of the velocity of the plane in item 1 is 240 m/s as given in the initial information.
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 magnitude of the velocity is sqrt(5) times the horizontal component. This results in a velocity vector that is inclined at an angle of arctan(2) ≈ 63.43 degrees with respect to the horizontal.
Is it true that you find acceleration when initial velocity final velocity and time are given?
Yes, acceleration can be calculated when initial velocity, final velocity, and time are given using the formula: ( a = \frac{{v_f - v_i}}{{t}} ), where ( a ) is acceleration, ( v_f ) is final velocity, ( v_i ) is initial velocity, and ( t ) is time.
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?
The magnitude of the initial velocity can be found using the Pythagorean theorem: square root of (horizontal velocity^2 + vertical velocity^2) = square root of (18.2^2 + 21.3^2) = square root of (330.28 + 454.69) = square root of 784.97 ≈ 28.0 m/s.
How do you calculate the change in velocity of a falling object?
The change in velocity of a falling object is calculated by subtracting the initial velocity from the final velocity. The acceleration due to gravity is typically involved in this calculation. The formula for calculating the change in velocity is: change in velocity = final velocity - initial velocity.
Spaceship 1 and spaceship 2 have equal masses of 300 kg spaceship 1 has an initial momentum magnitude magnitude of 900 kg ms what is its initial speed?
The initial speed of spaceship 1 can be calculated using the formula: momentum = mass x velocity. Thus, velocity = momentum / mass. Plugging in the values, the initial speed of spaceship 1 is 3 m/s.
The formula to find the magnitude of acceleration?
The formula to find the magnitude of acceleration is given by a = (v_f - v_i) / t, where a is acceleration, v_f is final velocity, v_i is initial velocity, and t is time. This formula calculates the rate at which the velocity of an object changes over time.
What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time
