The car's speed decreases by 60 - 40 = 20 mps in 10 seconds.
It's average acceleration is -20/10 = -2 mps/ps.
The acceleration is negative as the car is slowing down.
The formula for this situation is v = u + ft where v is the final velocity (40), u is the initial velocity (60), t is the time period (10) and f is the acceleration.
Then, 40 = 60 + 10f :
10f = 40 - 60 = -20 :
f = -20/10 = -2.

What is the acceleration of a car that accelerates from 44ms to 88ms over a period of 11 seconds?
Average acceleration = (change in speed) / (time for the change) = (88 - 44) / (11) = 4 meters per second2

The average speed during that period is 500 meters per second.

An eagle accelerates from 15 meters per second to 22 meters per second in 4 seconds. What is the eagle's average acceleration?
Average acceleration is the amount of acceleration per unit of time that a thing or an object undergoes. It is simple to discover. To find the average acceleration, we need only find out how much acceleration occurred and over what period of time. If we have the starting and the ending speeds, then by subtracting them we can find the chane of acceleration. Then we can divide that acceleration by the time it took to occur. The eagle in our example accelerates from 15 m/s to 22 m/s over a period of 4 seconds. His total acceleration was 7 m/s (22 m/s minus 15 m/s = 7 m/s), and, since it took 4 seconds to increase his speed by 7 m/s, the average acceleration is the total acceleration divided by the time it took to happen (as was stated). The average acceleration is 7 m/s divided by 4 seconds or 1.75 meters per second.
A car traveling at 25 meters a second speeds up to 40 meters a second over a period of 15 seconds what is the average acceleration of the car?
Average acceleration = (change in speed) divided by (time interval)A = (40 - 25) / 15 = 15/15 = 1 meter/sec2

What is the period of a 0.85m long pendulum?
The period of a pendulum can be calculated using the equation T = 2π√(l/g), where T is the period in seconds, l is the length of the pendulum in meters, and g is the acceleration due to gravity (9.81 m/s^2). Substituting the values, the period of a 0.85m long pendulum is approximately 2.43 seconds.
What is the acceleration of a car that slows down from 60 ms to 40 m s during a period of 10 seconds?

If a trucks brakes are applied for 2 seconds giving it acceleration of -3.1 ms2 what will the trucks new speed be in ms?
No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.
What does accelaration mean?
Acceleration is a change in velocity over time. When you accelerate in a car, you increase the speed in which you are going. Similarly, when slowing down your car by pressing the brakes, you are decelerating. This occurs when your final speed is lower than your initial speed. A simple way to calculate average acceleration within a time period is to use this equation: [Acceleration] = ([Final Velocity] - [Initial Velocity]) / [Time of Acceleration] If a person was to be traveling 5 meters per second, and then they accelerated to 10 meters per second in a time period of 5 seconds, their acceleration would be: A = (10m/s - 5m/s) / 5s = 1m/s2 This acceleration is equivalent to going from a jog to an all-out sprint in five seconds.
What is the formula you use to dertermine acceleration?
Acceleration (a) is calculated by dividing the change in velocity (Δv) by the time taken (Δt) over which the change occurs. Mathematically, it can be represented as: a = Δv / Δt. The SI unit of acceleration is meters per second squared (m/s^2).
What is the period of a simple pendulum 45 cm long on the Earth?
The period of a simple pendulum can be calculated using the formula T = 2π * sqrt(L/g), where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity. On Earth, the value of g is approximately 9.81 m/s^2. Converting the length of the pendulum to meters (0.45 m), the period would be about 1.42 seconds.
What are the effects of acceleration due to gravity on the time period of a pendulum?
The period of a pendulum (in seconds) is 2(pi)√(L/g), where L is the length and g is the acceleration due to gravity. As acceleration due to gravity increases, the period decreases, so the smaller the acceleration due to gravity, the longer the period of the pendulum.
