Q1. Sea Launch mission planners are going to launch their Russian launch vehicle from a Lo = 3 degrees into LEO with an inclination of 34 degrees and the longitude of ascending node of 124 degrees. Current LST at the launch site is 1140. a. How many launch opportunities will there be per day? b. What is the launch window location angle for both opportunities? c. What is LWSTAN? d. How long until the LWSTAN? e. What is the launch azimuth for ascending node? e. What is LWSTDN? f. How long until LWSTDN?
Q2. A man swings his child in a circle of radius 0.75 meters. If the mass of the child is 25 kilograms and child makes one revolution in 1.50 seconds, what is the magnitude and direction of the force that should be exerted by the man on the child?
A 73 kg parachutist descends during a vertical height of 420 m with constant speed. Find the increase in entropy produced by the parachutist; assume the air temperature is 21°C.
A 100-kg halfback running north with a speed of 12 m/s is tackled by a 110-kg opponent running south with a speed of 4.0 m/s. If collision is completely inelastic and head-on, compute the speed of the players just after the tackle.
What is the lift (in newtons) by reason of Bernoulli's principle on a wing of area 77 m^2 if the air passes over the top and bottom surfaces at speeds of 270 m/s and 140 m/s, correspondingly.
What is the charge on each
How far will it travel before becoming airborne
A 258-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.980, and the log has ..
pipe open at one end only has a fundamental frequency of 237 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Currently, when both pipes vibrate at their fundamental frequencies, a beat ..
Two projectiles are thrown with the same initial speed, one at an angle with respect to the level ground and the other at angle 90 degree. Both projectiles strike the ground at the equivalent distance from the projection point. Are both projectiles i..

A force vector points at an angle of 50.6° above the +x axis. It has a y component of +280 newtons. Calculate the magnitude of the force vector.
What will transform in terms of the observable properties of the black hole as this process continues
A certain car battery with a 14.0 V emf has an initial charge of 195 A•h. Assuming that the potential across the terminals stays constant until the battery is completely discharged, for how long in hours can it deliver energy at the rate of 184 W.
