Question

A 7150 kg truck traveling east at 5 m/s collides with a 1700 kg car traveling 30⁰ south of west at 20 m/s. After the collision at what angle do the two vehicles move. Express you answer in degrees from the positive x-axis. Use a coordinate where north is the +y axis and east is the +x axis.

Expert Solution

Step 1

Given quantities:

mass of truck (M) = 7150 kg

mass of car (m) = 1700 kg

Let, the initial velocity of truck be denoted as 'v₁' , the initial velocity of car be denoted by 'v₂' and the final velocity of truck and car combined be 'V'

Using the co-ordinate axis as mentioned in the question, the velocities in component form can be written as :
