PT. 3 HELP 40 POINTS You are a traffic accident investigator. You have arrived at the scene of an accident. Two trucks of equal mass (3,000 kg each) were involved in a rear-end accident at a stop sign. Here is what you know:
• Truck 1 started from rest at the top of a 22-meter hill and coasted toward the intersection.
.
Truck 2 was on a flat stretch of road at the bottom of the hill directly in front of Truck 1.
At the bottom of the hill, Truck 1 was going 20 m/s; Truck 2 was going 35 m/s.
.
There were no skid marks left by Truck 2. The collision occurred at the stop sign where Truck 2 had
stopped
• After the collision, both trucks moved together in the same direction at 10 m/s before slowly rolling
to a stop.
You must now push Truck 2, using 1,000 N of force, 8 meters off to the side of the road so no one
else gets hurt.
1. How much energy did truck 1 LOSE in the collision? 2. How much energy did truck 2 GAIN in the collision? 3. Which of the two laws of covered in this unit- law of conversion and momentum or law of conservation of energy- is obeyed in this problem, explain your reasoning! 4. How much work did it take to move truck 2 off the side of the road? 5. If it took you 40 seconds to move truck 2 off the road how much power did you expend? 6. Which simple machine does a truck have that helped you move truck 2? Explain. ALSO!!! I have one that's not answered yet for 20 points, less questions
