Zero, a hypothetical planet, has a mass of 5.0 × 10 23 kg, a radius of 3.0 × 10 6 m, and no atmosphere. A 10 kg space probe is to be launched vertically from its surface, (a) If the probe is launched with an initial energy of 5.0 × 10 7 J, what will be its kinetic energy when it is 4.0 × 10 6 m from the center of Zero? (b) If the probe is to achieve a maximum distance of 8.0 × 10 6 m from the center of Zero, with what initial kinetic energy must it be launched from the surface of Zero?

A 10 kg space probe is to be launched vertically from its surface, (a) If the probe is launched with an initial energy of 5.0 × 107 J, what will be its kinetic energy when it is 4.0 × 106 m from the center of Zero? (b) If the probe is to achieve a maximum distance of 8.0 × 106 m from the center of Zero, with what initial kinetic energy must it be launched from the surface of Zero?
A car driving at 27m/s veers to the left to avoid a deer in the road. The maneuver takes 2.0s and the direction of travel is altered by 20 degrees. What is the average acceleration during the constant speed maneuver? Do this in accordance with the example in the chapter.
