How would I solve these?

The Mars Rover has a mass of 1335.21 kg. If the acceleration due to gravity on Mars' surface is -3.}'5 misz, the magnitude of the Rover's weight on Mars, expressed in scientific notation, is b '10"N. The value of l: is . (Record all three digits of youranswer on the answer sh eet.) 0n planet 518:3, a 450-9 golf ball has a weight of.98'| N. The gravitational eld strength on planet 5180 is kag. (Record your three-digit answer on the answer sheet.) A 5.00 kg mass is riding on a horizontal platform that is rotating with a period of 3.00 s. The mass is held in place by the friction at a distance of 5.20 m from the centre of rotation. The coefcient of friction between the mass and the platform must be at least . {Record your two decimal answer in the box.)
