Aplayer passes a basketball to another player who catches it at the same level from which it was thrown. the initial speed of the ball is 7.1m/s and it travels a distance of 4.6m. what were (a) the initial direction of the ball and (b) it's time of flight?

horizontal direction ; Time of flight = 0.65seconds.

Explanation:

Initial direction: horizontal direction.

Time of the flight= velocity is (distance/time)

Speed= 7.1m/s

Distance= 4.6m

Time= X

Time = (Distance/speed)

X = (4.6 / 7.1) = 0.65 seconds

Time of flight = 0.65seconds.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
