force equals mass times acceleration....you need a unit of time here
so force = 2000kg x 25/(number of seconds)
Acceleration = (change in speed) divided by (time for the change) = (30/6) = 5 m/sec2
Force = m A = (2,000) (5) = 10,000 newtons
What is true meaning of the law of acceleration? If you mean Newton's 2nd law which states that a force causes a mass to accelerate. Acceleration measures how fast your velocity changes. I will give you an example. If you know a child with a wagon, this could be fun. The child is sitting on the wagon. Right now the child is at rest (velocity =0). He does not like being at rest, so he asks you to push him. As you push him he giggles, oh what fun. He is now moving (v = 6 m/s, not 0). Your friend said, "Do that again, and I will time how many seconds it takes for you to get him going that fast." It took 2 seconds for you to reach a velocity of 6 m/s. That means you were accelerating at a rate of 3 m/s each second. When you push the wagon, you exert a force, which causes the child and wagon to accelerate. Newton's 2nd law states that a force causes a mass to accelerate 1) Your push is the force. 2) The child and wagon are the mass. 3) The acceleration is the result. As a formula, Force = mass * acceleration I hope this helps
The idea here is to use Newton's Law, F=ma. Solving for acceleration: a = F/m. The number of seconds is irrelevant if all you want to calculate is the acceleration.
It is technically impossible to accelerate to the speed of light. That would require an infinite amount of energy. However, based on a simple, linear equation: Going from 0-60 mph in 4.2 seconds is an average acceleration of about 6.38 m/s2. The speed of light is 299,792,458 m/s. This gives us a result of about 46,943,164 seconds, or 1yr 178da1hr46min. (rounded)
Acceleration = (change in speed) divided by (time for the change) = (0 - 36)/3 = -12 m/s2The acceleration of gravity is 9.8 m/s2, so the passengers are pulled forwardagainst their seat belts with a 'force' of 1.22 Gs during the screech.
25 waves are produced in 20 seconds , so 25 ÷ 20 = 1.25 waves in 1 second ... so the Frequency is 1.25 Hz
Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds

answer is 20

Her average acceleration is 2.2 meters per second per second (2.2 m/s2 ).

20 miles/hour/second The acceleration is simple division 60/3 = 20.
A thoroughbred can accelerate to 60 miles per hour in 5.5 seconds. They can reach 45 miles per hour in 2.5 seconds.
Jack is driving a car. As he passes post 1 he is travelling at 15ms-1 and starts to accelerate at a steady speed. 8 seconds later he passes post 2 travelling at 30ms-1. Post 1 and 2 are What is his acceleration during this time?
The formula for finding time based on acceleration and speed is: (Delta)t = (Delta)v/a Change in time = change in speed / acceleration t = 75-15 / 20 t = 60 / 20 t = 3 seconds
