Question
1)The Moon takes 27.3 days to complete one revolution around the Earth (sidereal month). Assuming the orbit is circular with a radius of 3.85 × 108 m, calculate the centripetal acceleration experienced by the Moon.
2)A particle describes a circular trajectory with a radius of 0.4 m and its speed is constant. Knowing that it performs five revolutions per second,
determine:
-its speed.
-its acceleration.
3)A hunter uses a stone held by a strap (sling) as a weapon to capture prey that strays from him. The stone rotates above him in a uniform circular motion 1.60 m in diameter, the frequency of which is three revolutions per second.
-What is the centripetal acceleration of the stone?
-How fast will the stone leave the slingshot?
Ps: the picture is the first question answer.
