Question

A 5,000 kg truck is travelling west and runs into the rear of a 1,000 kg car that was stationary. The truck and car are locked together after the collision and move west with velocity of 18 m/s. What is the velocity of the truck before the collision?

Expert Solution

Step 1

$mass of truck (M) = 5000 k g initial velocity of the truck along west direction = u mass of car (m) = 1000 k g initial velocity of the car = 0 \frac{m}{s} Final velocity of the combination of truck and car (v) = 18 \frac{m}{s} (a l o n g w e s t)$
