Inelastic Collisions in One Dimension: a 2

question 23

Multiple Choice

Inelastic collisions in one dimension: A 2.00-kg object traveling east at 20.0 m/s collides with a 3.00-kg object traveling west at 10.0 m/s. After the collision, the 2.00-kg object has a velocity 5.00 m/s to the west. How much kinetic energy was lost during the collision?

• A) 0.000 J
• B) 458 J
• C) 516 J
• D) 91.7 J
• E) 175 J

Definitions:

Exponential Smoothing

A time series forecasting method for smoothing data points by giving more weight to recent observations while exponentially decreasing the weights for older observations.

Forecast Errors

Discrepancies between the forecasted and actual values in demand forecasting, reflecting the accuracy of predictions.

Time-series Data

A sequence of data points collected or recorded at time-ordered intervals, often used for forecasting or statistical analysis.

Random Variations

Unpredictable fluctuations that affect data or processes, not attributable to any known cause.
