A good quarterback can throw a football at 27m/s;m/s (about 60mph;mph ).?

HERE THE ANSWERS 👇

• Maximum range is achieved if the ball is thrown at 45 degrees to horizontal.

  Initial vertical V component = (sin 45 x 27) = 19.1m/sec.

  Time to max. height = (v/g) = 19.1/9.8 = 1.949 secs.

  b) Double it, = 3.898 secs. time in air.

  Horizontal launch V component = (cos 45 x 27) = 19.1m/sec.

  a) Max. range = (19.1 x 3.898s) = 74.45 metres.

• A) R = V²/g = 74.4 m = 81.3 yd

  B) t = √2*V/g = 3.9 sec
