Question 2 A H An inclined track is secured to a table. The height of the highest point of the track above the tabletop is h₁. The height from the tabletop to the floor is h₂. A block of mass M is released from rest and slides down the track such that all frictional forces are considered to be negligible. The block leaves the track horizontally and strikes the ground at a distance D from the edge of the track as shown. Which of the following statements is correct about the scenario? Select two answers. B C h₁ D n₂ If the block is released from a height 2h₁, the block will land at a distance 2D away from the end of the track. If the block's mass is increased to 2M, the block will land at a distance 2D away from the edge of the track. D- The total mechanical energy of the block-Earth system remains constant. The total mechanical energy of the system containing only the block increases from the moment of release to the moment it strikes the ground.

Why is the following situation impossible? In a new casino, a supersized pinball machine is introduced. Casino advertising boasts that a professional basketball player can lie on top of the machine and his head and feet will not hang off the edge! The ball launcher in the machine sends metal balls up one side of the machine and then into play. The spring in the launcher (Fig. P6.60) has a force constant of 1.20 N/cm. The surface on which the ball moves is inclined = 10.0 with respect to the horizontal. The spring is initially compressed its maximum distance d = 5.00 cm. A ball of mass 100 g is projected into play by releasing the plunger. Casino visitors find the play of the giant machine quite exciting.
