A"sun yacht" is a spacecraft with a large sail that is pushed by sunlight. although such a push is tiny in everyday circumstances, it can be large enough to send the spacecraft outward from the sun on a cost-free but slow trip. suppose that the spacecraft has a mass of 900 kg and receives a push of 20 n. (a) what is the magnitude of the resulting acceleration? if the craft starts from rest,(b) how far will it travel in 1 day and (c) how fast will it then be moving?

Suppose that a comet that was seen in 563 a. d. by chinese astronomers was spotted again in year 1951. assume the time between observations is the period of the comet and take its eccentricity as 0.986. what are (a) the semimajor axis of the comet's orbit and (b) its greatest distance from the sun?

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

Could someone . i have tried to solve myself but my calculation is off
