Acertain rocket of initial mass mo carries 60% of its initial mass as fuel. what is its final speed if it accelerates from rest in free space, as it burns all of its fuel? express your answer in multiples of the fuel velocity out of the rocket, a. b) supos this rocketsul in inth brms mass of 03 m f fel. then jettisons the first stage fuel tank with a mass of 0.1mo. then, it burns the remaining 0.3mo of fuel. find the final speed, assuming ver does not change.

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
