Problem B.3: Interplanetary Journey A space probe is about to launch with the objective to explore the planets Mars and Jupiter. To use the lowest amount of energy, the rocket starts from the Earth's orbit (A) and flies in an ellip- tical orbit to Mars (B), such that the ellipse has its perihelion at Earth's orbit and its aphelion at Mars' orbit. The space probe explores Mars for some time until Mars has completed 1/4 of its orbit (C). After that, the space probe uses the same ellipse to get from Mars (C) to Jupiter (D). There the mission is completed, and the space probe will stay around Jupiter. The drawing below shows the trajectory of the space probe (not drawn to scale): A Sun / Earth Mars Jupiter Below you find the obrital period and the semi-major axis of the three planets: Orbital period Semi-major axis 365 days Earth 1.00 AU Mars 687 days 1.52 AU Jupiter 4333 days 5.20 AU How many years after its launch from the Earth (A) will the space probe arrive at Jupiter (D)?

Question No. 4 A boy is standing inside a train moving with a constant velocity of magnitude 10 m/s. He throws a ball vertically up with a speed of 5 m/s relative to the train. Find the radius of curvature of the path of the ball just at the time of projection. (Take g 10m/s) ) 14 m )7m 5 m 10m
Thruth or false 1. The gravitational field is a vector quantity. 2. You spin around your head a small mass on a rope. If you increase the radius while maintaining the same pull force on the string, you will see the frequency of the mass decrease. 3. All masses (even a person!) generate their own gravitational fields. 4. There is a point between two masses where the gravitational field is zero. 5. A mass requires a gravitational field only in space. 6. Two astronauts initially at rest in space will be accelerated towards each other since there is a gravitational force between the two.
1. Consider the arbitrarily shaped object shown in the figure to the right undergoing a uniform circular motion in the xy plane about a fixed axis that is perpendicular to the xy plane. Point O is located in the xy plane along the axis of rotation and P is a fixed point on the object located at a distance r from the point O. If the magnitude of velocity vector of point P is v= 1.3 m/s, and the radius of its circular path is r = 0.65 m, determine: (a) The angular velocity w of point P (b) The magnitude of acceleration vector a of point P 20 P n
You are driving in a car and you are sitting on a scale. You are travelling at constant speed of 20 m/s when you suddenly enter a dip with a radius of curvature of 100 meters. As you drive through this dip you and your car are executing Uniform Circular Motion You know that when you are standing on the scale on flat, non-accelerating ground that it says you are 660 Newtons. 100 m When you are in the very bottom of the dip (still traveling at 20 m/s), what does the scale you are sitting on read? Tips: Draw a free body diagram for your body when your car is at the bottom of the circular dip. If you are undergoing that special kind of motion, what should your forces sum to? That should help you find what you are looking for.

5. Consider an aircraft flying due east along the equator. Define an Earth-fixed coordinate system FE at zero longitude and zero latitude, and a local horizontal coordinate system F, fixed to the center-of-gravity (CG) of the aircraft. Describe the relationship between the axes of FE and FH at the instant the aircraft is at zero longitude and zero latitude, and again at the instant it is at 180 deg east longitude and zero latitude. 6. Assume the Earth (uniform sphere) has a diameter of 6875 NM (nautical miles, NM). The aircraft in Problem 5 is flying at 600 knots relative to an assumed stationary atmosphere, at a constant altitude of 2 NM. Find {@7}# and {w#}#• EC
