# A ball falls straight down through the air under the influence of gravity. There is a retarding force\(F\) on the ball with magnitude given by\(F=bv\), where v is the speed of the ball and\(b\)is a positive constant. The ball reaches a terminal velocity after a time\(t\).

A ball falls straight down through the air under the influence of gravity. There is a retarding force \(F\) on the ball with magnitude given by \(F=bv\), where \(v\) is the speed of the ball and \(b\) is a positive constant. The ball reaches a terminal velocity after a time \(t\). The magnitude of the acceleration at time \(t/2\) is

- **A.** Increasing
- **B.** Decreasing
- **C.** Neither increasing or decreasing.
- **D.** \(10 \, \text{m/s}^2\)
- **E.** Zero
