Ahelicopter, starting from rest, accelerates straight up from the roof of a hospital. the lifting force does work in raising the helicopter. an 700-kg helicopter rises from rest to a speed of 11.0 m/s in a time of 3.0 s. during this time it climbs to a height of 9.6 m. what is the average power generated by the lifting force?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Which statement correctly describes the current in a circuit that is made up of any two resistors connected in parallel with a battery? a. the current in the battery and in each resistor is the same b. the current the battery equals to the sum of the currents in the resistors c.the current in the battery is less than the current in either resistor d. the current in the battery equals to the product of the currents in the resistors
