Q2 (40 marks) The girl throws 0.8 kg ball toward the wall with an initial velocity Va-15m/s as shown in Fig 2. Parameters are given in Fig. 2. Ball is considered as a particle and there is not friction between the ball and the wall 1. Determine the velocity of the ball at which it strikes the wall at B 2. Calculate the velocity of the ball at which it rebounds from the wall if the coefficient of restitution e 0.6 3. Determine the distance s (see Fig. 2) from the wall to where it strikes the ground at C. (10 marks) (15 marks) (15 marks) UA = 15 m/s 30° 1.5 m 4 m
