Question

An enemy ship appears on your radar screen! You send out a radar ping, which is a signal

that travels through space at a constant velocity, bounces off an object, and then returns to
your ship. The radar ping moves at 300,000,000 m/s. You send out the signal and it takes
0.00026667 seconds for the signal to return; how far away is the enemy ship?

Answer 1

Answer:d=80,001 m

Explanation:df = di + Vave(t)

d = 0 + 300,000,000(0.00026667)

d = 80,001 m
