Areconnaissance plane flies 556 km away from its base at 832 m/s, then flies back to its base at 1248 m/s. what is its average speed? answer in units of m/s

We use the formula, to calculate the average speed of the round trip,

Here, , is total distance covered by plane in total time, .

For the round trip,

.

Thus,

.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
