ll B, moving in the positive direction of an x axis at speed v, collides with stationary ball A at the origin. A and B have different masses. After the collision, B moves in the negative direction of the y axis at speed v/3. In what direction does A move, as an angle with respect to the x axis?

3. Consider the Phillips curve: Π = EΠ - B(u - uⁿ) + v

   Π = inflation           EΠ =expected inflation        v=supply shock

      u=unemployment rate     u^N=natural unemployment rate

Explain the effect on the Phillips curve and the Phillips curve tradeoff due to the Covid 19 virus.

Calculate the molar entropy of Krypton at 298.15K and 1 bar. Assume it behaves as a
monatomic ideal gas with m = 0.08308 kg mol-1 and the degeneracy of the ground
electronic state equal to one.
Hint:
Q(N, V, T)= 1/N![(2πmkBT)/h^2] V^N*gel

A spacecraft arrives at Mars’ sphere of influence with a heliocentric velocity of 22 km/s and a heliocentric fight-path angle of 10 deg. When the spacecraft reaches the periapsis of its Mars-centric arrival trajectory, at an altitude of 200 km, it performs a ∆V to circularize its trajectory. What is the required ∆V ?

Question 1: Given a graph with length l(e) on edges, find a minimum length paths from a vertex s to V −s so that among all shortest lengths paths from s to V −s we find the ones with minimum number of edges.

Use Dijkstra's algorithm

Using C++, write a program to calculate the height and velocity of a ball thrown upward at a user-specified height and speed in 10 seconds. Position (h) and velocity (v) of the ball as a function of time are given by the equations: h(t) =(1/2)gt² + v₀t + h₀ v(t) = gt + v₀

Design an O(nlogn) algorithm that takes two arrays A and B (not necessarily sorted) of size n of real numbers and a value v. The algorithm returns i and j if there exist i and j such that A[i] + B[j] = v and no otherwise. Describe your algorithm in English and give its time analysis.

A poll was taken this year asking college students if they considered themselves overweight. A similar poll was taken 5 years age. Five years age, a sample of 270 students showed that 120 considered themselves overweight. This year a poll of 300 students showed that 140 considered themselves overweight. At a 5% level of significance, test to see if there is any difference in the proportion of college students who consider themselves overweight between the two polls. What is your conclusion?
