Sounding Rocket Trajectory. Sounding rockets are used to probe different levels of the atmosphere to collect information such as that used to monitor the levels of ozone in the atmosphere. In addition to carrying the scientific package for collecting data in the upper atmosphere, the rocket carries a telemetry system in its nose to transmit data to a receiver at the launch site. Besides the scientific data, performance measurements on the rocket itself are transmitted to be monitored by range safety personnel and to be later analyzed by engineers. These performance data include altitude, velocity, and acceleration data. Assume that this information is stored in a file and that each line contains contains four values: time, altitude, velocity, and acceleration. Assume that the units are s, m, m/s, and m/s2, respectively.

Modify the program in problem so that it prints the times that correspond to the firing of each stage. Assume that the firing corresponds to the point at which the velocity begins to increase.
