Question

(1) . A planet orbits a star in a circle. By Kepler's 2d aw of planetary motion the planet s speed is constant. If the radius of the orbit is 1.50x10 m and it takes s complete an orbit, what are the magnitude and direction of the acceleration o f the planeti? (2) A dangerously careless student ignores safety regulations and rotates a metal probe in a circular motion experiment far faster than the safety limit in his Ia breaks and the probe flies off horizontally, narrowly missing his lab partner the floor 10.0 meters away. If the heig 1.25 meters and the radius of the circle apparatus broke was 20 cm, what was the centripetal acceleration of the probe just before the apparatus broke? b book. The apparatus and landing on ht of the circular platform with the experiment was in which the probe was moving before the (3) The probe bounces off the laboratory floor so that the vertical component of its velocity becomes the negative of what it had been. What is the vertical component of the momentum transferred to the laboratory floor? (4) Suppose that the planet in problem (1) had a moon orbiting it and that at a given time the planet was at a position 106X10 km i + 106X10° km j and the moon exerted a force on the planet of 1.8X1020 Ni+ 5.4X10 N k. What would the torque of the moon on the planet be?

Answer 1

Here we shall solve Question 1.

This question is based on the concept of

1. Velocity of planet in circular path

2. acceleration of planet

3. direction of acceleration

4. mathematical simplification
