Due in 30 help me please ​

1. Fc = 14212.3 N = 14.21 KN

2. ac = 1579.14 m/s²

Explanation:

First, we  will find the linear velocity of the ball:

where,

v = linear velocity = ?

r = radius of circle = 2.5 m

ω = angular speed = (4 rotations/s)(2π rad/1 rotation) = 8π rad/s

Therefore,

2.

Now, the centripetal acceleration can be given as:

where,

ac = centripetal acceleration = ?

Therefore,

ac = 1579.14 m/s²

1.

The centripetal force can be given as:

Fc = 14212.3 N = 14.21 KN

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

true
