Ask your teacher cam newton of the carolina panthers throws a perfect football spiral at 6.9 rev/s. the radius of a pro football is 8.5 cm at the middle of the short side. what is the centripetal acceleration of the laces on the football? (enter the magnitude in m/s2.)

Explanation:

It is given that,

Angular speed of the football spiral,

Radius of a pro football, r = 8.5 cm = 0.085 m

The velocity is given by :

v = 3.68 m/s

The centripetal acceleration is given by :

So, the centripetal acceleration of the laces on the football is . Hence, this is the required solution.

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

dang that balls went far
