Question
![A block of mass \( m \) is pulled by a rope along a horizontal surface with negligible friction. For time \( t > 0 \), the magnitude of the acceleration of the object as a function of time is given by the equation \( a = Ae^{-kt} \), where \( A \) and \( k \) are positive constants. Which of the following expressions determines the impulse exerted on the block by the rope during the time interval \( 0 < t < t_1 \)?
Options:
- (A) \( A \int_{0}^{t_1} e^{-kt} dt \)
- (B) \( mA \frac{d}{dt} [e^{-kt}]_{t_1} \)
- (C) \( A \frac{d}{dt} [e^{-kt}]_{t_1} \)
- (D) \( mA t_1 [e^{-kt}] \)
