A solid uniform sphere of mass 1.85 kg and diameter 45.0 cm spins about an axle through its center. Starting with an angular velocity of 2.40 rev/s, it stops after turning through 18.2 rev with uniform acceleration.
The net torque acting on this sphere as it is slowing down is closest to A) 0.00593 N m.
B) 0.0372 N m.
C) 0.0466 N m.
D) 0.0620 N m.
E) 0.149 N m.
Question 2
If there were no gravity, a ball thrown upward at an angle would follow a straight-line path. Due to gravity, however, at the end of 2 s it is

B) 10 m below the straight line.
C) 15 m below the straight line.
D) 20 m below the straight line.
E) more than 20 m below the straight line.
