Atypical tam 210 student opens up their lunchbox to find that they packed their favorite lunch: an engineering potato. instead of eating the special potato, our student decides to apply forces to the potato to see what happens. given the following: f 1 =< 2 , − 2 > n f 2 =< − 1 , − 1 > n f 3 =< − 0.6 , 0 > n x 1 = 0.09 m x 2 = 0.09 m y 1 = 0.2248 m y 2 = 0.135 m y 3 = 0.09 m replace the force system acting on the potato with a single force and moment applied at the origin. what are the magnitudes of the single force and moment? f = 3.0265 n

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
