The drawing shows three particles far away from any other objects and located on a straight line. the masses of these particles are ma = 363 kg, mb = 517 kg, and mc = 154 kg. find the magnitude and direction of the net gravitational force acting on each of the three particles (let the direction to the right be positive).

particle a is 0.5m from b and b is .25m from all in a astraight line

Identical marbles are released from the same height on each of the following four frictionless ramps . compare the speed of the marbles at the end of each ramp. explain your reasoning

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
