Two objects are being lifted by a machine. One object has a mass of 2 kg, and is lifted at a speed of 2 m/s. The other has a mass of 4 kg and is lifted at a rate of 3 m/s. c. Which object had more potential energy when it was lifted a distance of 10 m? d. What does this tell you about the variable(s) that impact gravitational potential energy?

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
