As discussed in class, the moon is receding from the Earth due to tides at a rate of ~4 cm/year. Let’s assume that rate has been constant throughout time (it wasn’t, but we can use it to illustrate some key points). Its current semi-major axis is 384,400 km.a) If the moon formed 4.5 billion years ago and has been receding from the Earth ever since, what was its original semi-major axis? What was its original orbital period?b) What would the apparent size of the Moon have been in the sky as viewed from Earth? That is, in Hmwk 2, you were told the diameter of the Moon spans about 0.5o when viewed from Earth today. What would it have been when the Moon first formed?

Using what you know about uniform circular motion and your equations, answer the questions below. What happens to the centripetal force if the mass increases by factor of 2 and speed and radius are held constant? What happens to the centripetal force if the velocity decreases by factor of 4 and mass and radius are held constant? What happens to the radius of the circle if the centripetal force decreases by factor of 2 and mass and speed are held constant?
Let's say for the purpose of this question that a softball pitcher completes one perfect revolution during her fast pitch. The pitcher's arm is 0.81585 m, and she completes her pitch in 0.9s, what is the velocity of the ball as it travels around the arc? Assume she keeps her arm extended throughout the pitch, and round your answer to two decimal points. What is the centripetal acceleration of the softball?
A parent holds their child’s hands and swings them around in a circle, The child is at a 42-degree angle with the vertical as they spin in the circle. The child has a mass of 17kg. What is the name of the centripetal force in this situation? (be specific! If it’s a component, make sure to mention that) What is the magnitude of the centripetal force? What is the total tension on the child? What is the centripetal acceleration of the child as they move in a circle? If the radius of the circle is 0.75m, what is the speed of the child as they are swung in a circle?

A rocket coasts in an elliptical orbit around Earth. To attain the greatest amount of KE for escape using a given amount of fuel, should it fire its engines to accelerate forward when it is at the apogee or at the perigee? (Hint: Let the formula Fd = Δ KEbe your guide to thinking. Suppose the thrust F is brief and of the same duration in either case. Then consider the distance d the rocket would travel during this brief burst at the apogee and at the perigee.)
ANSWER QUICK! Ive read the honor code and it says that their a question can have up to 3 subparts (i.e. part a, b, and c). So please answer all questions. A skier leaves the ramp of a ski jump with a velocity of 11.4m/s, 16.2 degrees above the horizontal. The slope below is inclined downwards at 53.3 degrees, and air resistance is negligible. Calculate the distance from the ramp to where the jumper lands (in meters). Calculate the velocity x component just before the landing (in m/s). Calculate the velocity y component just before the landing (in m/s).
