Is mass times acceleration equals velocity squared dimensionally correct?

No. Fortunately, that equation doesn't appear anywhere in Physics.
[mass] times [acceleration] has the dimensions [mass] x [length/time2],
and that's exactly [force] which makes everything beautiful.

If a car goes in 6.8 seconds how do you figure out the acceleration?
Acceleration= distance / velocity squared
How is average velocity different from acceleration?
For a start, acceleration doesn't even have the same units as velocity: acceleration is a velocity divided by time, so while speed or velocity have units of [distance]/[time], acceleration has units of [distance]/[time squared]
How is the radius of rotation related to the centripetal force and angular velocity?
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
Why do we a use the units meters per second squared when we talk about acceleration?
For every second of acceleration the velocity is increased by that acceleration.
If an object travels for 15 minutes at a constant velocity of 12 miles per hour west what is its acceleration?
Since acceleration is a change in velocity, if your velocity is constant (does not change), your acceleration is zero.
How do you find displacement when you only have acceleration initial velocity and final velocity?
Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)
The si unit of velocity is the meter per second squared true or false?
The answer is FALSE- acceleration would be correct
Why the second is squared in acceleration?
it is very simple........... velocity or speed = distance / time. acceleration = velocity / time but, we know that velocity = distance / time so just substitute the equation of velocity in acceleration...... so, finally we get , acceleration = distance/time*time so it is time squared.

What is the velocity if travel 5.7 meters per second squared for 4 seconds?
Velocity can be measured in metres per second, not metres per second squared. Acceleration is measured in metres per second squared but knowing only the acceleration does not help in finding the velocity.

What is acceleration time graph?
The change in the velocity divided by time in meters per second squared.
How do you find acceleration if only given a velocity?
If you have an initial and final velocity and time you can figure it out with this equation, Vf squared=Vi squared1/2a(t squared) If you don't have those you cannot find acceleration. However the acceleration on Earth is a constant -9.81

Since acceleration is a change in velocity, if your velocity is constant (does not change), your acceleration is zero.
What is the homogeneity of v2 equals u2 plus 2as?
Each term in the equation has dimensions of velocity-squared (remember "a" here is acceleration which is velocity divided by time, so "as" is velocity x distance / time = velocity squared).
