A (1000-mathrm{kg}) car traveling east at (50 mathrm{~km} / mathrm{h}) passes over the top of a hill
Question:
A \(1000-\mathrm{kg}\) car traveling east at \(50 \mathrm{~km} / \mathrm{h}\) passes over the top of a hill and hits a \(3000-\mathrm{kg}\) truck stalled in the middle of the lane. The impact causes the truck to roll eastward at \(15 \mathrm{~km} / \mathrm{h}\).
(a) What is the coefficient of restitution for the collision? During the collision, how much kinetic energy is converted to internal energy \((b)\) in the Earth reference frame and \((c)\) in a reference frame moving at \(5 \mathrm{~km} / \mathrm{h}\) eastward along the road?
Fantastic news! We've Found the answer you've been seeking!
Step by Step Answer:
To solve this problem well first find the velocity of the car and truck after the collision Then well use the coefficient of restitution to calculate the kinetic energy converted to internal energy Gi...View the full answer
