A2000-kg car going 30 m/s collides head-on with a 5000-kg truck going at the same speed. if the truck comes to a halt, the car's final velocity is

So, as we the data given and we need to calculate the final velocity,v₂ of the mass,m₁ inside the collision with m₂. So, as we know the value of v₁ and m₁, then we can have the results by placing all the values inside the formula.

Explanation:

The formula given to us in case of elastic collision:

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

find the sum of the two horizontal vectors and the sum of the two vertical vectors
