Answer #1

using 1st equation of motion to find velocity before it hit the ground in absence of air

v = u + at

since the object dropped, so, u = 0

v = 9.8* 5 = 49 m/s

now given that

terminal velocity = 0.5 * v = 8.5*49 = 24.5 m/s

==========

Do comment in case any doubt, will reply for sure . Goodluck

    A 200 gram foam ball is propelled from ground level into the air with an initial velocity of 13 m/s at an angle of 37 degrees from horizontal (+x direction). Halfway through its flight, it strikes a giant yellow bird flying at 8 m/s in the -x direction. This causes the ball's velocity to be reduced by 20% but it continues flying thru the air. The bird loses one feather but is ok and continues flying at 7 m/s. After...
