I need some help with part b
Compute the impact speed of a body released from rest at an altitude h = 336 mi. (a) Assume a constant gravitational acceleration g_0 = 32.2 ft/sec^2 and (b) account for the variation of g with altitude. Neglect the effects of atmospheric drag.

As a body is projected to a high altitude above the earths surface, the variation of the acceleration of gravity with respect to alitude y must be taken into account. Neglecting air resistance, this acceleration is determined from the formula a -go R2 /(R + ν , where g.-9.81 m/s 2 e constant gravita or al acceleration at se a la e R-E 56 m s e radius of he earth and the positive d rection is measured upward.

Question 1. An aircraft is flying West along the equator (as shown in Fig.1) with a constant speed equal to 800 km/h with respect to the Earth surface, at an altitude equal to 10 km. The radius of the Earth is equal to 6371 km. On the Figure 1 (see printable on Page 3), define (draw) the following a) Earth-fixed coordinate system with the origin at zero longitude and zero latitude (point OE in Fig. 1); Vehicle-carried coordinate system; Body-fixed...

Questions 1 &2
This is a more challenging problem with constant acceleration. Simply plugging numbers into an equation gets us nowhere, so something extra is required. On a movie set, a red car and a green car are to move toward each other on opposite sides of a highway lane divider line, as indicated in the figure. Green car Example 2.4.4 Figure 1 When the drivers pass each other, the driver of the red car is to toss a package...

Question 2 According to Newton's Laws of Motion, if I throw a baseball in outer space - far from any other object- how will that ball move over time? (For the sake of this problem, let's neglect my mass) After the force of my hand no longer acts on the ball: Question 2 options: the ball will move forward, but it will gradually slow down and come to a stop once the force of my hand no longer acts on...
