Question

the ball and the pendulum cup have the same velocity after the collision. As is the case with any collision, total momentum is conserved (unchanged). Using conservation of momentum, write down an equation for Vealefore in terms of the velocity of the hall together with the pendmcu ( d the mass of the al and that of the cup (meup). ball before= Using conservation of energy between 2 and a, another equation relating Vater and θ can be found. Write down this equation, and combine it with (1) to obtain an equation for Vsall before in terms of 6, Rom, mcup and moal Part 2 In this part the steel ball is shot horizontally and allowed to follow its natural parabolic trajectory until it strikes the floor, as shown in the diagram. If you measure the horizontal displacement 'R' and the vertical displacement 'H', you can find Vball beforeby the usual method discussed in the textbook chapterH on projectile motion, solving the y- displacement equation for the time of fall, and using this time in the x-displacement equation Neglect air resistance, of course, so that the horizontal velocity component remains constant.) The value of Vball beforeobtained with this method should agree to within a few percent with that obtained in Part 1. Figure 2 Write down here the equation for Vbll before in terms of H and R Typical results of Vbaledfare are between 450 and 500 m/sec. Seek help if your results are far out of this range. 14-2
