Answer:
25.8 rad/s
Explanation:
C = circumference of the hollow sphere = 0.749 m
r = radius of the sphere
Circumference of the hollow sphere is given as
C = 2π r
0.749 = 2 (3.14) r
r = 0.12 m
m = mass of the basketball = 0.624 kg
Moment of inertia of basketball is given as
I = 5.99 x 10⁻³ kg-m²
w = angular speed
KE = Kinetic energy of the ball = 1.99 J
Kinetic energy of the ball is given as
KE = (0.5) I w²
1.99 = (0.5) (5.99 x 10⁻³) w²
w = 25.8 rad/s
