Answer:
Tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s
Explanation:
From the question above,
(1) tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s
Mometum = mass×velocity
Momentum = 270×0.5
Momentum = 135 kgm/s
(2) hare with a mass of 2.7 kg moving at a velocity of 7 m/s
Mementum = mass × velocity
Momentum = 2.7×7
Momentum = 18.9 kgm/s
(3) turtle with a mass of 91 kg moving at a velocity of 1.4 m/s
Momentum = mass × velocity
Momentum = 91×1.4
Momentum = 127.4 kgm/s
(4) roadrunner with a mass of 1.8 kg moving at a velocity of 6.7 m/s
Momentum = mass × velocity
Momentum = 1.8×6.7
Momentum = 12.06 kgm/s
From the above, the one with the greatest momentum is tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s
Answer: Magnetic and gravitational force
Explanation: When a magnet and an iron nail are kept at a distance,the magnet attracts the nail without touching using magnetic force. In this example, the magnet and the nail are interacting.
The earth pulls the moon towards it and keeps it in orbit without touching it, using gravitational force. In this example,the moon and the earth are interacting.
