Using one of the three laws of mechanical motion : v2 = u2 + 2as, where v is the final velocity, u is the initial velocity, a is the acceleration, s is the distance. Then,
0 = 202 + 2 x (-1)s : 2s = 400 : s =200 meters.
The puck will travel 200 meters.

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).
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.
How do you square velocity?
While you cannot physically square your velocity, such as you are traveling at 10 meters per second, and then there's another dimension where you are 100 meters squared per second squared, velocity squared comes up in various physics calculations. Kinetic energy of an object in motion is (1/2)*mass*(velocity squared). This just means that you take the velocity and square the number, and also square the units, so (10 m/s)2 = 100 m2 / s2 for the calculation.
5.7 meters per second squared for 4 seconds what is velocity?
It is not possible to answer this question without the starting velocity.
What is acceleration time graph?
The change in the velocity divided by time in meters per second squared.

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)
What are units for velocity squared?
The SI unit for velocity is m/s. Therefore the SI units for velocity squared would be m2/s2.
How do you calculate mass when given joules and velocity?
Kinetic energy = (1/2) (mass) (velocity squared)Divide each sideby (velocity squared/2): Mass in kg = ( 2 x energy in joules) / (velocity in m/s) squared
The friction on an object moving through water or air is?
Dynamic drag (in both air and water) resistance is proportional to the velocity squared, but due to its higher viscosity water offers a higher resistance force ( object and velocity being the same for both).
What is the homogeneity of v2 equals u2 plus 2as?

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.
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
