    Velocity
In summary, a 0.160-kg hockey puck with an initial velocity of 2.98m/s is moving on an icy, frictionless, horizontal surface. The problem asks to calculate the magnitude of the velocity after a force of 24.0N is applied to the right for 5.5×10−2s. Alternatively, if a force of 12.5N is applied to the left from t=0 to t= 5.5×10−2s, the problem asks for the magnitude of the final velocity. Relevant equations and concepts involve calculating the final velocity using the given force and time.

FAQ: Calculating Velocity of a Hockey Puck

What is the formula for calculating velocity of a hockey puck?

The formula for calculating velocity of a hockey puck is velocity = distance / time, where velocity is measured in meters per second, distance is measured in meters, and time is measured in seconds.

What equipment is needed to measure the velocity of a hockey puck?

To measure the velocity of a hockey puck, you will need a stopwatch or timer, a measuring tape or ruler, and a hockey puck.

Can velocity be calculated at any point during the puck's motion?

Yes, velocity can be calculated at any point during the puck's motion as long as the distance and time are known.

How is velocity affected by the surface the puck is sliding on?

The surface the puck is sliding on can affect the friction and therefore the speed of the puck. A smoother surface will result in a higher velocity compared to a rougher surface.

What are some factors that can affect the accuracy of velocity calculations for a hockey puck?

Some factors that can affect the accuracy of velocity calculations for a hockey puck include human error in measuring distance and time, variations in the surface the puck is sliding on, and external forces such as air resistance or wind.
