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.
What is its average acceleration over the first 5.1s of its motion?
To find the average acceleration over the first 5.1 seconds of motion, divide the change in velocity over that time period by the time taken. Calculate the final velocity minus the initial velocity over 5.1 seconds to find the average acceleration.
A skydiver slows down in 54 ms to 4 ms by opening his parachute if it takes 0.75 What is is the magnitude of the skydivers acceleration?
To find the acceleration, we first calculate the change in velocity: 4 m/s - 54 m/s = -50 m/s. Next, we use the formula for acceleration: acceleration = change in velocity / time = -50 m/s / 0.75 s = -66.67 m/s^2. The magnitude of the acceleration is 66.67 m/s^2.
Starting from rest a ball rolls down a long incline with a constant acceleration After 2 seconds it traveled 2 meters In the next second it will have travled?
In the first 2 seconds, the velocity of the ball would be given by v = at, where a is the acceleration. Given it traveled 2 meters in 2 seconds, we can use the equation s = (1/2)at^2 to find the acceleration which is 1 m/s^2. So, after 3 seconds, the ball will travel an additional 3 * 1 = 3 meters.
A dog is running at 6.45 m/s. His human calls to him and 3.19 seconds later he is running at 6.56 m/s. What is his acceleration during this time?
0.034 m/s/s

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
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
Why does your 2003 cadillac deville front end vibrate with acceleration?
If it's ONLY during acceleration I'd check the CV joints first.
