Ball 1 has mass m1=2m and is moving toward the positive x-axis with velocity v. It makes a head-on elastic collision with a stationary ball 2 of mass m2= m. After the collision their speeds (vr and vz) are: O a. v/3, 4v/3 Ob -v/3, 2v/3 O c. v/2, 3v/2 O d. -v/2, v/2 Question 11 A wheel is initially rotating at 10 rad/s and has a constant angular acceleration. After 10 s it has rotated through 300 rad. Not yet Its angular acceleration (in rad/s) is: answered O a. 2 Marked out of 1.50 O b. 6 P Flag question O .4 O d. 8 Ball 1 has mass m1=2m and is moving toward the positive x-axis with velocity v.
