What is the first derivative of speed?
Speed is scalar (it doesn't have direction), and the magnitude of velocity (a vector). The first derivative of velocity is acceleration, therefore the first derivative of speed is the magnitude of acceleration.
A ball thrown vertically upward returns to the starting point in 8 seconds.find its initial velocity.?
A ball thrown vertically upward returns to the starting point in 8 seconds.-- Its velocity was upward for 4 seconds and downward for the other 4 seconds.-- Its velocity was zero at the turning point, exactly 4 seconds after leaving the hand.-- During the first 4 seconds, gravitational acceleration reduced the magnitude of its upward velocity by(9.8 meters/second2) x (4 seconds) = 39.2 meters per second-- So that had to be the magnitude of its initial upward velocity.
A 34.1 kg child rides a Ferris wheel whose diameter is 18.3 m When the ride is turning at a constant rate the child's speed has a constant value of 4.23 ms Find the normal force the seat exerts?
First calculate the acceleration: the magnitude of circular acceleration is velocity2/ radius.Then use Newton's Law: force = mass x acceleration.
A stone falls freely from rest. How far does it fall during the first 10 seconds?
490 meters
What is the relationship between acceleraion and velocity?
Acceleration increases the velocity. There are two physics formulas that you can use to see more how they interact. The first is a formula for determining your current velocity at a given moment t, knowing your initial velocity and your current acceleration. v = v0 + at (v0 is v-naught. The zero is usually written as a subscript.) You can solve this equation for a to get a formula for acceleration as well. a = (v-v0)/t So, basically, at any given interval t, the acceleration has been added onto the current velocity that many times.

A rock dropped on the moon will increase its speed from 0 ms its starting speed when first dropped to 4.9 ms in about 3 seconds What value do you calculate for the magnitude of the acceleration o?
1.63 m/s2

What is the magnitude of the acceleration of an object free falling for 3 meters in the first second on a planet with no atmosphere?
The magnitude of acceleration depends on the gravitational pull from the planet. The amount of gravitational pull depends on the size and mass of the planet. On Earth gravity will produce an acceleration of 9.8 meters per second squared if there was no atmosphere.
How do you calculate magnitude and direction of a object or truck?
-- First of all, you calculate the magnitude and direction of vectors. An object or a truck are not vectors. Things like their weight, velocity, and acceleration are. -- There are different methods and formulas for calculating each different vector. For example: . . . The truck's weight is (the truck's mass) x (the acceleration of gravity) downward . . . The truck's acceleration is (the rate at which its speed changes) in the direction in which its speed changes.
A rock dropped on the moon will increase its speed from 0 ms its starting speed when first dropped to 49 ms in about 3 seconds What value do you calculate for the magnitude of the acceleration o?
Acceleration = (change in speed) divided by (time for the change).From the figures given in the question, the acceleration is ( 49/3 ) = 16.33 m/sec2 .There's no way that this is happening on the moon. That acceleration is about 67% greaterthan the acceleration of gravity on the earth's surface. It should be about 83% less, or about 1.63 m/sec2.I see the problem now. The '49' in the question should be '4.9'.apex- 1.63 m/s2
Why does your 2003 cadillac deville front end vibrate with acceleration?
If it's ONLY during acceleration I'd check the CV joints first.
If a skydiver reaches terminal speed after ten seconds will the skydiver gain more speed during the first second or the ninth second?
I would imagine that it is uniform acceleration up until terminal speed. However, wind resistance will be higher 10000 feet up, so acceleration may be less at the start
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
A first magnitude star is times brighter than a 5th magnitude star?
For apparent magnitudes, a magnitude of zero has the same magnitude as Vega. A first magnitude star is 40 percent as bright and a fifth magnitude star is one percent. So, a first magnitude star is 40 times as bright as a fifth.
Is the skydiver increasing or decreasing his speed during the first 3 seconds?
Increasing.
What is the acceleration of a car that goes from 40 kmhr to 80 kmhr in 2 seconds?
First, convert the speeds to SI units, that is, to meters/second. Then, simply subtract the difference in speed by the 2 seconds. The result will be in meters/sec2.
