Newtons second law lab

For y = 0 the firing angle which optimizes a projectile's range is 45 degrees. For y < 0 (landing below the firing point), as in this experiment, would you expect the firing angle which optimizes the range to be greater than or less than 45 degrees? Carefully explain why.

M Gmail O YouTube A Maps O RCAP QUESTION 2 Problem A new type of force was discovered by physicists with the following expression: α Fnew + Be* + 3x^ where alpha & beta are constants, and x is the position. The expression above was obtained from the interaction of a massless Higg s Boson (a type of particle) and a black hole. Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do to achieve this feat? (For simplicity, consider that no energy is lost in the process) Solution To determine the work done we apply the following W = Fx dx Evaluating the above, we get W = aln | x beta e X 3/5 5 for the limits from x¡ to xf substituting x1 and x2 as the limits, the work done is expressed as W = | + X1 e ( x15 x2 ) x2 MacBook Pro

How would I answer part D?

1. Answer each problem following the proper format (GIVEN, REQUIRED, SOLUTION). 2. Do not round off intermediate values when using them to solve subsequent values; however, they may be written up to 4 decimal places in your answer sheets. Final answers should be rounded off up to 4 DECIMAL PLACES. 3. Box the final answers.

Hi, Could you please check your answer for part a? The answer cannot be 6.648E-26 N. Thanks!

I Review Newton's law of gravity and Coulomb's law are both inverse-square laws. Consequently, there should be a "Gauss's law for gravity." Part A The electric field was defined as E = Fon g/g, and we used this to find the electric field of a point charge. Using analogous reasoning, what is the gravitational field g of a point mass? Write your answer using the unit vector r, but be careful with signs; the gravitational force between two "like masses" is attractive, not repulsive. Express your answer in terms of the variables M, r, unit vector î, and the gravitational constant G. Use the 'unit vector' button to denote unit vectors in your answer. • View Available Hint(s)
