What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
If a rock is dropped and it's speed increases from 0 to 4.9 in about 3 seconds. what is the acceleration?
Assuming that your units of velocity are in units/second Acceleration = (velocity 2 - velocity 1) / time Acceleration = (4.9 - 0) / 3 Acceleration =1.63 *With correct significant figures the answer is 2
Acceleration is defined as a change in velocity over time if a runner increases velocity from 2 m s to 4 m s over a period of 20 seconds what is the acceleration?
Assuming that acceleration is constant during that time, just divide the change in speed by the time.
What is positive accelerations?
Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position. If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.
Hits a speed of 50 m s after 5 seconds what is his rate of acceleration?
If he started out from "rest" (zero speed), then his average acceleration for the 5 seconds is50/5 = 10 meters per second2
What is the amount by which the speed increases in one second?
It is the acceleration.
What is the the amount by which the speed increases in one second called?
It is the acceleration.
How does a change in speed affect acceleration?
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
Why speed increases if its acceleration decreases?
stamina
What is the acceleration if the velocity increases by eighty meters per second in twenty seconds?
Average acceleration = (change in speed) divided by (time for the change)= (80) / (20) = 4 meters per second2
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
When a ball increases in speed by the same amount each second its acceleration is?
When a ball increases in speed by the same amount each second, its acceleration is constant. This type of motion is known as constant acceleration.
What increases speed during a given interval of time?
acceleration
What is the amount by which the speed increases in one second called?
It is the acceleration.
What is the definition of deceleration acceleration?
Deceleration is the rate at which an object slows down or decreases its speed. Acceleration is the rate at which an object speeds up or increases its velocity. Both are measures of how quickly an object's motion changes.

A car traveling at a speed of 25 ms increases its speed to 30.0 ms in 10.0 seconds. what is the magnitude of its acceleration?
The acceleration of the car can be calculated using the equation: acceleration = change in velocity / time taken. The change in velocity is 30.0 m/s - 25.0 m/s = 5.0 m/s. The time taken is given as 10.0 seconds. Plugging these values into the equation gives an acceleration of 0.5 m/s^2.
