Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

For the helicopter of Prob. 11.168, it was found that when the helicopter was at B , the distance and the angle of elevation of the helicopter were r= 3000 ft and 0= 20°, respectively. Four seconds later, the radar station sighted the helicopter at r= 3320 ft and 0= 23.1°. Determine the average speed and the angle of climb β of the helicopter during the 4-s interval.

After taking off, a helicopter climbs in a straight line at a constant
angle 6. Its flight is tracked by radar from point A. Determine the
speed of the helicopter in terms of d, ß. 0, and è.
O B
