As Uranus occults a star the relative motion between Uranus and Earth is 23 km/s. An observer on Earth sees the star disappear for 37 minutes and 2 seconds, and notes that the center of Uranus passed directly in front of the star. 1. Based on these observations, what value would you calculate for the diameter of Uranus? 2. How would the result be different if the center of Uranus had not passed directly in front of the star? 3....

Binary Stars Q1) A binary star system has a distance from Earth of 42.2 light years. The distance between the stars is 1.08 x 101 m and the rotation period is 104 days. Assume equal masses of the stars, and circular orbits (centre of mass of the system is at rest relative to the Earth). a) Calculate the speed of the stars relative to the centre of mass of the system. Further assume the...

At time t = 0 s, a rock is thrown vertically upward from the ground. At time t = 1.6 s, it passes the top of a tall tower. 0.80 s later, it reaches its maximum height. Q)How fast is the rock moving as it passes the top of the tower? A car moving with constant acceleration covers the distance between two points 120 m apart in a time of 8.0 s. Its speed at the second point is 12...
An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground.
a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall with...
