A skater has outstretched arms preparing for a turn with a moment of inertia of 2.56 kg m2

. When the arms are joined the body moment of inertia around the axis of

rotation is equal to 0.40 kg m2

. If the original angular speed of the skater is 0.40 rev/s, what is

the final angular speed?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
