Rosita weighed 50 n when she traveled to mars, a planet with an acceleration due to gravity that is about one-third as large as earthâs acceleration due to gravity. about how much does rosita weigh on earth?

What is the magnitude of the acceleration vector which causes a particle to move from velocity −5i−2j m/s to −6i+ 7j m/s in 8 seconds. answer in m/s.

Which is the correct symbol for an isotope of iodine with 53 protons and 78 neutrons?

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
