Question

A5 kg football is launched 45 degrees above the horizontal at a speed of 26 m/s.

What is the time of flight for the football from the point it left the ground until it hit the ground?

Answer 1

time to teach the highest point t
V = u + at
0= 26 Sin (45) - 9.8 t
9.8 t = 18.4
t = 1.88 seconds.
Total time in flight = 2 x 1.88 = 3.76 s
