Homework Statement mass of star = 2.53 x 1030 kilograms mass of planet = 5.25 x 1024 kilograms mass of moon = 8.09 x 1022 kilograms average distance from star to planet = 1.14 x 1011 meters average distance from planet to moon = 4.59 x 108 meters Use the data above to determine the net...

If we, say had something the mass of a rock, and then one of a small asteroid, which one would fall faster to the earth?

That's great I think I got it. Here is one problem that makes no sense to me even after using the given hint. 2. A car moving at 13.7 meters per second crashes into a barrier and stops in 0.277 meters. a. How long does it take to stop the car? Hint: This is a constant acceleration problem. So...

Brett takes a slap shot, exerting an average force of 16.8 Newtons on the puck for 0.116 seconds. The puck has a mass of 0.110 kilograms and was initially moving directly away from the goal at 3.4 meters per second. How fast does it move toward the goal? 21.127 or -21.127 is not the correct...

These two problems are giving me some guff. Any ideas on how to solve? Two cars approach an intersection of perpendicular streets. Car A is moving north at 10.5 meters per second, and Car B is moving west at 17.1 meters per second. What is the velocity of Car B relative to Car A? (In other...

Well, for number 2 I divided 409 meters per second in 1.99 and 409 by 2.32. In theory, I would think this would give me a negative answer for part 5 since we are braking. According to my internet assignment, these answers are not right. I got a-205.5276382 b--176.2931034 Must I do some...

Okay, I am new to physics and for some reason I am not connecting the dots. I would appreciate if a combination of anyone could explain these solutions. I know the 4 kinematics equations but am really unsure if I need to know other things...like the rate at which objects will always fall or...
