Ahollow steel ball weighing 4 pounds is suspended from a spring. this stretches the spring 17 feet. the ball is started in motion from the equilibrium position with a downward velocity of 4 feet per second. the air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second) . suppose that after t seconds the ball is y feet below its rest position. find y in terms of t. (note that the positive direction is down.) take as the gravitational acceleration 32 feet per second per second.

Explanation:

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

there is no correct list among the choices you've provided.

the list might look something like this:

-- piccolo

-- flute

-- soprano singer

-- trumpet
