circular motion. 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:
Phobos – the moon of Mars mass = 1.08 1016 kg radius ≈ 12 km how large is the orbital speed around Phobos ?
