Answer: Solor cycles and tings
Answer:
2 revolutions.
Explanation:
We need to obtain the angular velocity when he is in the air.
The angular momentum is given by:
Because of angular momentum conservation L1=L2, so the final angular velocity is given by:
We need to calculate the time the skater is in the air, so we need to use the formula of parabolic motion:
so the time taken is 1.26s
the angular displacement is given by:
the number of revolutions is given by:
the skater execute two complete revolutions in the air.
The law of universal gravitation says that one object attracts every other object using a proportional force to the mass of the object.
