hello I need help solving those questions please thank you so much in advance!

' ' u (6) A 2.58 kg sphere makes a perfectly inelastic collision with a second sphere that is initially at rest. The composite system moves with a speed equal to one third the original speed of the 2.58 kg sphere. What is the mass of the second sphere? Submit Answer Tries 0/10 0 a Water falls at the rate of 278 9/5 from a height of 58.3m into a 723g bucket on a scale (without splashing). If the bucket is originally empty, what does the scale read 3175 after the rst drop of water reaches the bucket? Submit Answer Tries 0/10 \" a A 2.65kg steel ball strikes a massive wall at 10.9m/s at an angle of a = 68.6' with the plane of the wall. It bounces off with the same speed and angle. If the hall is in contact with the wall for 0.214s, what is the magnitude of the average force exerted on the ball by the wall? Submit Answer Tries 0/10
