2D Motion - Comparing the path of projectiles on Earth and Mars Imagine you are repeating the "Land the Rover" experiment on Mars. How would the experiment differ than the one done on Earth? You'd have to include a discussion of the how HLPs behave on Earth (more "gravity" and lots of air friction) vs Mars (less "gravity" and hardly any air friction). Include, at least, a set of graph stacks to help in the comparison.

Forces/2D Motion - HLP and the ISS
Revisit the physics of the ISS...how did it get into near-Earth orbit? Why are astronauts "weightless"? How is the ISS really like a HLP? How did Isaac Newton usher in the concept of launching satellites with his "Newton's Cannon" thought experiment? Address the physics of the ISS through the lens of 2D Motion and Forces.

Try c ? that’s what i got

Magma  is composed of molten rock and is  stored  in the earth's crust. lava is  magma  that reaches the surface of our planet through a volcano vent.

    m₁v₁ + m₂v₂ = (m₁ + m₂)vmomentum is conserved.the left-hand side of the equation represents the momentum in the system before the collision.the right-hand side represents the momentum in the system after the collisionm₁ and v₁ represents the mass and the velocity of the physics blockm₂ and v₂ represents the mass and velocity of the ball of puttyv represents the final velocity of the combined mass.the question states the two masses stick together. they combined mass has its own velocity with the body mass the sum of the two objects' massestheir combined momentum is (m₁ + m₂)vto find the magitude of (m₁ + m₂)v, we need to add the vectors on the left-hand side of the equation: m₁v₁ + m₂v₂.note the diagram. i have positioned the vectors in accordance with their directions.the magnitude of the resultant can be calculated using the pythagorean theorem since this is a right triangle situation (north and west are perpendicular)|(m₁ + m₂)v| =  √[ (m₁v₁)² + (m₂v₂)² ]|(m₁ + m₂)v| =  √[ (1.5kg·8.0m/s)² + (0.40kg·20m/s)² ]|(m₁ + m₂)v| =  14.4 kg m/sfor two significant figures (assuming that 20m/s is two), this rounds to 14 kg m/s

45 is the correct answer
