Aparachutist's speed during a free fall reaches 180 kilometers per hour. what is this speed in meters per second? at this speed, how many meters will the parachutist fall during 20 seconds of free fall? do not round your answers.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
