Questions and exercises AstroBlaster ---- the Multiple Collision Accelerator (This toy is available in the lab, play it before you answer the following questions). 1. Take the smallest ball (red) out of the AstroBlaster and hold it at arm's length from your body, then drop it at Smallest ball (red) heighth, . The ball will be bounced upward after it hits the ground and reaches a height ha . Use the energy and momentum conservation laws to prove that h, shy. Figure 4. AstroBlaster 612. Follow the three steps and instructions shown in Fig. 5 to play the toy "AstroBlaster", in which the step 3 shows that the smallest ball (red) will reach a height of hg . Assume all the collisions are elastic and the air resistance can be neglected. Use the energy and momentum conservation laws to prove: As = ( # | 4 22 40, where MI and m are the masses of the AstroBlaster and the smallest red ball respectively. Step 1: Hold tip of AstroBlaster's rod which Step 2: Release when Step 3. The smallest AstroBlaster is hanging extends through the ball (red) will reach a straight down. smallest ball (red).
