A hockey puck moves with velocity of 20meters per second If the friction of the ice retards the puck 1 meters per second squared How far will it go before it stops?

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).
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.
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.
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 calculate Velocity squared?
Velocity squared is calculated by multiplying the velocity of an object by itself. For example, if the velocity of an object is 10 m/s, then the velocity squared would be 10 m/s * 10 m/s = 100 m/s^2.
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 find displacement when you only have acceleration initial velocity and final velocity?
You can use the equation: Displacement = (final velocity squared - initial velocity squared) / (2 * acceleration). Plug in the values of final velocity, initial velocity, and acceleration to calculate the displacement.
What is velocity squared?
Velocity squared is the velocity of an object multiplied by itself. It represents the kinetic energy of the object. Mathematically, it can be expressed as v^2, where v is the velocity of the object.
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).
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 the Friction force due to motion through a gas or liquid?
The friction force due to motion through a gas or liquid is called drag force. It is caused by the resistance of the fluid to the object moving through it and is proportional to the object's velocity squared and the fluid's viscosity.

Cart is rolling down a special ramp where there is no friction at all What will happen if the amount of mass on the cart is increased?
If the mass of the cart is increased, the kinetic energy of the cart will also increase as it rolls down the ramp. The velocity of the cart will increase as well, since the kinetic energy is directly proportional to both mass and velocity squared.
5.7 meters per second squared for 4 seconds what is velocity?
It is not possible to answer this question without the starting velocity.
State in words how acceleration is calculated?
There are two methods, it depends on what variables you have: 1. Subtract the initial velocity from the final velocity and divide that whole term by the time (Vf- Vi)/t = a 2. Square both the initial velocity and the final velocity and subtract the squared inital velocity from the squared final velocity and that answer by two times the distance (Vf^2 - Vi^2)/2d = a
