If you have issues D Question 16 A ball is thrown vertically upward. Assume there is no air resistance. As it is rising: O its gravitational potential energy is not conserved, buts its momentum is conserved. both its momentum and its mechanical energy are conserved. both its momentum and its kinetic energy are conserved. its momentum is not conserved, but its mechanical energy is conserved. its kinetic energy is conserved, but its momentum is not conserved.

Question 17 1 pts Block A and B are on a frictionless surface. Both blocks have the same mass. Before the collision block A travels to the right with speed v, while B travels to the left with speed 2v. After the collision, both A and B travel to the left with speed v. There is/are one or more external force(s) acting on this system. The net external force on the system is zero. There are no external forces on this system. It cannot be determined whether external forces act without knowing the internal forces between the two objects in the collision.

D Question 20 1 pts Imaging a ruler of length L of uniform mass, with the axis of rotation at its center. A mass M is hanged at a distance 1/4L to the left of its center, another mass M is hanged at a 1/4L to the right of its center. The right side of the ruler is initially hold at an angle of 30 degree below the horizontal. After the rule is released from rest, it will rotate counterclockwise rotate clockwise stay in the same position Previous Not saved Sub esc @ # 3 A 5 6 HH Q CC E LL R T C A S D F G H L O 2 Z X C B E II IT
