A crane uses a cable to lift and lower an 845 kg mass. Compute the tension in the cable under the following conditions:
1. As it is being lifted, the speed of the mass increases by 2.5 m/s each second.
2. The mass is lifted at a speed of 15 m/s.
3. The mass is stationary.
4. As it is being lowered, the speed of the mass increases by 2.5 m/s each second.
5. The mass is lowered at speed of 5 m/s.
