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

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Determine the maximum r-value of the polar equation r =3+3 cos 0

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
