What is the formula for calculating final velocity when you know the initial speed and the acceleration?
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
How do you find acceleration with velocity given?
Use the formula Acceleration = (final velosity - initial velocity)/ time.
How do you find initial acceleration.?
The initial acceleration of an object can be found by calculating the change in velocity over time. This can be done by dividing the final velocity by the time taken to reach that velocity. The formula for initial acceleration is: initial acceleration = (final velocity - initial velocity) / time.
How do you calculate power when given speed acceleration weight and distance?
Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.
How do you find acceleration when given only mass and velocity?
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.

How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
How do you find acceleration with velocity given?
Use the formula Acceleration = (final velosity - initial velocity)/ time.
How do you find final speed if acceleration time and beginning velocity is given?
(acceleration X time) + beginning velocity = final speed
A ball starts at rest accelerates uniformly and travels 250m in 5 seconds What is the final velocity and the acceleration of the ball?
The final velocity can be calculated using the formula final velocity = initial velocity + (acceleration * time). Since the ball starts at rest, the initial velocity is 0. The final velocity = 0 + (acceleration * 5). To find the acceleration, you can use the formula acceleration = (final velocity - initial velocity) / time. The final velocity is unknown, but we just calculated the final velocity is equal to 5 times the acceleration, so acceleration = (final velocity - 0) / 5. Substituting the final velocity = 5 times the acceleration into the acceleration equation, we get acceleration = (5 * acceleration - 0)/5. Solving for acceleration, we get acceleration = 1 m/s^2. The final velocity is 5 m/s.
How do you find initial acceleration.?
The initial acceleration of an object can be found by calculating the change in velocity over time. This can be done by dividing the final velocity by the time taken to reach that velocity. The formula for initial acceleration is: initial acceleration = (final velocity - initial velocity) / time.
How do you find acceleration from speed?
If speed does not change, then acceleration is 0 To find acceleration, you must also know the time Speed = metres per second. Acceleration = meters per second, per second Therefore you can use the equation m/s2 to find the acceleration. change in speed/ change in time.
Near the end of page 124 of your reading material you are shown a calculation to determine a car's final speed after accelerating for four seconds?
The calculation involves using the formula: final speed = initial speed + (acceleration x time). Input the initial speed and acceleration values, then multiply acceleration by time before adding it to initial speed to find the final speed after four seconds of acceleration.
A speed bike tops a hill at 3.50 ms an accelerates steadily down the hill until reaching a speed of 11.4 ms after 4.20 second how far did the bike travel durig this period?
You can find the distance traveled by the bike by using the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. In this case, the initial velocity is 3.50 m/s, the final velocity is 11.4 m/s, the time is 4.20 seconds, and since the bike is accelerating, you can find the acceleration using the equation: acceleration = (final velocity - initial velocity) / time. Plug these values into the formula to find the distance traveled.
What is the expression for average acceleration?
Acceleration = Change in velocity divided by the change in time. This formula only works if velocity is constant. If velocity is not constant, find the acceleration for both points in time. Then add the two accelerations and divide by 2.
How do you calculate power when given speed acceleration weight and distance?
Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.
Is the formula for velocity different than the formula for speed?
The size of the velocity is the speed, and you calculate it the same way. But whenyou find the size of the velocity, you're not done yet, because you also need itsdirection.
