(c) How far is Mars from the Sun when its speed is the average of the aphelionand perihelion speeds? 1. Energy conservation can also be applied toplanets orbiting the Sun in an elliptical orbit.The figure shows the orbit of Mars aroundthe Sun. Point A is the maximum distancefrom the Sun and is called aphelion. Point Dis the minimum distance from the Sun and iscalled perihelion.sunA.(a) At aphelion, Mars is 2.49x10" m from the Sun and it has a speed of 22.0km/s. What is the kinetic energy of Mars at aphelion? What is its potentialenergy? What is its mechanical energy? Mars has a mass of 6.42x103 kgand the Sun has a mass of 1.99x100 kg(b) At perihelion, Mars is 2.07x10"m from the Sun. What is Mars's speed atperihelion?

a). Given m=6.42x1023kg M=1.99x1030kg ra=2.49x1011m va=22.0km/s=22000m/s Now the kinetic energy of…

You are testing a new roller coaster ride in which a car of mass mm moves around a vertical circle of radius RR. In one test, the car starts at the bottom of the circle (point A) with initial kinetic energy KiKi. When the car reaches the top of the circle (point B), its kinetic energy is Ki/4Ki/4, and its gravitational potential energy has increased by Ki/2Ki/2. What was the speed of the car at point A, in terms of gg and RR? Express your answer in terms of the variable RRR and constant ggg vA=
