A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 890-kg helicopter rises from rest to a speed of 9.0 m/s in a time of 3.5 s. During this time it climbs to a height of 8.0 m. What is the average power generated by the lifting force?

A car, starting from rest, accelerates in the +x direction as in the figure. It has a mass of 1.10 × 103 kg and maintains an acceleration of +4.30 m/s2 for 4.10 s. Assume that a single horizontal force (not shown) accelerates the vehicle. Determine the average power generated by this force.
A helicopter accelerates upward, away from the surface of the earth, at 0.6 m/s2 while lifting a 1375.0 kg car. What is the tension in the cable (ignore the cable's mass), in N, that connects the car to the helicopter?
5. A car starting from rest moves in a straight line with a constant acceleration of 2.20 m/s? for 14.0 s, then slows down to a stop with a deceleration of 2.90 m/s2. How far does it travel? constant meters 6. Two cars are traveling along a straight road. Car (A) maintains a constant speed of 890 kmh; car (B) maintains a constant speed of 115 km/h. Att o, car (B) is 39.0 km behind car A. How far will...
A helicopter starts from rest at point A and travels along the straight-line path with a constant acceleration a. If the speed v = 33 m/s when the altitude of the helicopter is h = 44 m, determine the values of r, i, o, and as measured by the tracking device at O. At this instant, 0 = 38°, and the distance d = 159 m. Neglect the small height of the tracking device above the ground. ih А d...
Starting from rest, a truck travels in a straight line for 8.0 s with a uniform acceleration of +2.0 m/s2. The driver then applies the brakes for 2.0 s, causing a uniform acceleration of −3.0 m/s2 over that time. (a) What is the truck's speed at the end of the braking period? m/s (b) What is the total distance traveled by the truck (from the point where it started at rest to the end of the braking period)? m
