Problem 15.78 Using a slingshot, the boy fires the 0.3 lb marble at the concrete wall. striking it at B. Part A If the coefficient of restitution between the marble and the wall is e 0.6, determine the magnitude of the speed of the marble after it rebounds from the wall Express your answer with the appropriate units НА Value Units Figure 1 of 1 Request Answer Submit Part B Determine the directional angle between the speed of the marble...
B A A 145° 1.5 m e C! 30 m Using a slingshot, the boy fires the 100 g marble at the concrete wall, striking it at B. The coefficient of restitution between the marble and the wall is e=0.5. Case 2: if va= 30 m/s; 0 = 45° (20 points) a) Using theoretical methods to determine the velocity of the marble right before impact vb and its rebound velocity, v’B, the rebound angle 0. (8 points) Hint: To create...
