A probe and its equipment are weighed on the Earth, where g=10 N/kgg = 10\ \mathrm{N/kg}g=10 N/kg, before they are sent to Mars. On Mars they will rest together on a support. A calibration block on the surface of Mars is used to find the gravitational field strength there.
| Quantity | Value |
|---|---|
| Weight of probe on the Earth | 180 N |
| Weight of equipment on the Earth | 70 N |
| Mass of calibration block | 6.0 kg |
| Weight of calibration block on Mars | 22.2 N |
| Maximum total weight the support can hold | 90 N |
Calculate the weight of the probe on Mars.
Calculate the total weight of the probe and the equipment on Mars. Use your answer to explain whether the support can hold them.
