The mass of Jupiter is 4 x 1023 kg. If the mass of the Sun is 2 x 1030 kg and the sun and Jupiter are 7 x 1011 m apart, what is the force of gravity between the two?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

25pts the diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
