You are part of a team in an engineering class that is working on a scale model of a new design for a life vest. You have been asked to find the mass of a piece of foam that will be used for flotation. Because the piece is too bulky to fit on your balance, you break it into two parts. You measure the mass of the first part as 128.3 0.3 g and the second part as 77.0 0.3 g. a. What are the maximum and minimum values for the total mass you might reasonably report? b. What is the best estimate for the total mass of the foam? Hint: Propagation of uncertainty is described in Appendix A.
(II) Rain is falling at the rate of 2.5 cm/h and accumulates in a pan. If the raindrops hit at 8.0 m/s estimate the force on the bottom of a 1.02- m2 pan due to the impacting rain which we assume does not rebound. Water has a mass of 1.0 x103 kg per m3

During the US Open, a 56 g tennis ball is hit at 12.0 m/s. Considering, determine the maximum number of meters the ball will reach within 1.2 s.
The answer I have is 0 kg m/s, not 24 kg m/s. I was just not sure how to calculate to get 0 kh m/s. Can you recheck the problem to see if it was done correctly? Thanks.
I need help on this question the answer for question number one should be 31.93 kg.m^2 and for question 2 it's 1.68m from top and 3 sec.

3. On his walk home, Mr. Stark sees a wishing well. He takes out a 100 dollar bill, crumples it up into a ball and throws it upward over the well (at the level of the mouth of the well) and goes up 15 ft. 7 seconds after the bill leaves his hand, it reaches the bottom of the well which apparently didn't have any water after all. How deep is the well? What do you think he wanted to wish for?
