    Heating Mineral Water to 60°C Using Plain Water at 100°C

    Thanks but don't think that there are so much difference between them. Any other ideas?

    At what velocity should we bounce the ball

    It isn't in English so I think that it wouldn't help. But it is exactly like I posted. No more data and information that's why I really don't know how to solve it. (I was also quite surprised by the 3 seconds and the 1.5 m but it is correct.)

    At what velocity should we bounce the ball

    If we drop a ball from 1.5 m it is bouncing for 3 seconds. At what velocity should we bounce the ball in order to make it reach the height of 1.5 m?
