2. A 15. kg weight (m) is moving at a constant speed of 0.60 m/s up a ramp as it is pulled by a pulley and weight system. The tension force is 55 N. Assume there is no friction. Draw a force
diagram in the space provided for the weight my. Include component forces and angles. Properly
label each of the forces and indicate which (if any) of the forces should be equal.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° 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.)

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.

Humid air is a better electrical conductor than dry air. explain why you are most likely to receive a shock after walking across a carpet when the air is dry than when the air is humid.
