Question 7 2 pts A solid sphere, radius 20.0 cm and mass 1.57 kg, is rotating about an axis through its centre with angular velocity 6.02 rad s-¹. Calculate the rotational kinetic energy of the sphere, in J, to 3 d.p. Question 8 2 pts A blender has a rotating blade at the centre, which is what cuts and blends the food. If this blade has a constant angular acceleration of 1.73 rad/s², how much time does it take to reach an angular velocity of 37.1 rad/s, from rest? Give your answer to 2 d.p.
