I need help on question 7.4? 7.4. Given: A =4.0 m-2.0m-and B-[-5.2007].N=(a) Draw a diagram with both vectors starting at the origin and express both vectors asmagnitude and direction. What is the angle between the two vectors?(b) Show that Ẩ × B = 16 Nm 2 by using the formula |Ã||B| sin and the right-hand rule.(c) Find A x B by using matrix multiplication: (A, By – Ay Bx) 27.5. It's a rough approximation, but let's treat a spinning ice skater as a solid cylinder with aradius of 0.25 m.(a) If their mass is 55 kg, what is their rotational inertia?(b) Calculate the magnitude of the angular momentum of a 55 kg ice skater spinning 6 timesa second.(c) Calculate the total kinetic energy of this skater if they are spinning at a rate of 6 rotationsper second while traveling through the air at a rate of 2 m/s.

You are designing an RPG (role-playing game) for a gaming console and have decided to use an open world design, where players can explore the terrain freely, encountering enemies by chance. 8. Your design team has coded this in-game world to exist on the circle x² + y? < 900 Page 3 on the xy-plane. At any point (x, y) in this world you've also associated a danger function d(x, y) that measures how likely it is to encounter an enemy at that point. Thus high values of d(x,y) correspond to dangerous points, while low values of d(x, y) correspond to safe points. If d(x, y) = e¬a²y, find the safest point(s) and most dangerous point(s) in-game.

A probe of mass 100 kg is coasting through a dense gas cloud in deep space, where g = 0. There is drag from the gas cloud and it is modeled by the equation -0.38 v (N). If the probe entered the gas cloud with speed 1,047 m/s, how much time, in s, will it take for the probe's speed to be reduced to 14 percent of its initial velocity? (Please answer to the fourth decimal place)
