105. Comet Halley will be travelling about 1.5 km/s (almost 1 mile per second) in 2023 when it reaches aphelion. When it reaches perihelion in 2061, it will be sixty times closer to the Sun, so its speed will be about: (conserve angular momentum) a. 1.5 km/s b. 90 km/s c. 5400 km/s d. 0.025 km/s e. 0.0004 km/s

2) Planet Velocities and Energy (10 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation V2= GM.[(2/r) - (1/a)] Here Vis the speed of the body in m/s, G is the gravitational constant, M. is the mass of the Sun...

101. The mass of the Earth is almost 6.0x104 kg, and the average radius is about 6400 km. A satellite with a mass of 70 Kg is orbiting at an altitude of 600 km. Calculate the acceleration with which the satellite is falling on Earth. a. 5.7x10 m/s b. 5.7x10 m/s c. 5.7x10° m's d. 5.7x10 m/ e. 5.7x10m/s 102. The mass of the Earth is almost 6.0x 10* kg, and the average radius is about 6400...

1. A car accelerates from zero to 105 km/h in 5.21 s. What is its average acceleration in km/h/s and m/s? 2. An object moving in the x-direction has a position described by the function x(t) - 6.30t + 8.70t2, where t is in seconds and x is in meters. What is the acceleration as a function of time? The figure shows the graph of v vs t for the motion of a motorcyle that starts from rest and moves...

1. A train at a constant 62.0 km/h moves east for 32.0 min, then in a direction 46.0° east of due north for 29.0 min, and then west for 42.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip? 2. A cart is propelled over an XX plane with acceleration components ax 5.5 m/s2 and ay = -2.3 m/s. Its initial velocity has components vox = 9.3 m/s and voy...
