example hammer throw
example: hammer throw

max dist. ~ 75m

need to accelerate the hammer to a speed of about 30 m/s.

hammer mass = 7.3 kg

chain length = 1.2 m

what’s the tension in the chain?

P.S. now you know why hammer throwers are a bit on the hefty side…

rank in order from smallest to largest the free fall acceleration on the surgfaces of these planets
Rank in order from smallest to largest the free-fall acceleration on the surgfaces of these planets:
phobos the moon of mars
Phobos – the moon of Mars

mass = 1.08 1016 kg

radius ≈ 12 km

how large is the orbital speed around Phobos ?
