question 98

Multiple Choice

A weight is attached to a spring. Suppose the position (in meters) of the weight above the floor t seconds after it is released is given by $P ( t ) = 0.5 \sin \left( \pi t + \frac { \pi } { 2 } \right) + 1.2$ . What is the average rate of change of the position of the weight (in m/s) over the time interval [3, 5]?

• A)-1.7
• B)-1.0
• C)-0.5
• D)0
• E)0.5
• F)1.0
• G)1.7
• H)Cannot be determined
