A 0.500-kg sphere moving with a velocity expressed as
(a)

The final velocity of the
Answer to Problem 47AP
The final velocity of the
Explanation of Solution
According to the law of conservation of momentum,
Here,
Substitute
The final velocity of the heavier sphere is zero due to which the kinetic energy of the sphere is also zero. This is due to the loss of energy. Thus, the collision is inelastic.
Conclusion:
Therefore, the final velocity of the
(b)

The final velocity of the
Answer to Problem 47AP
The final velocity of the
Explanation of Solution
From equation (1), the law of conservation of momentum is,
Substitute
Conclusion:
Therefore, the final velocity of the
(c)

I am having trouble with this part of the lab.arrow_forwardMick and Rick are twins born on Earth in the year 2175. Rick grows up to be an Earth-bound robotics technician while Mick becomes an intergalactic astronaut. Mick leaves the Earth on his first space mission in the year 2200 and travels, according to his clock, for 10 years at a speed of 0.75c. Unfortunately, at this point in his journey, the structure of his ship undergoes mechanical breakdown and the ship explodes. How old is Rick when his brother dies?arrow_forward
