26. A constant force P = 750 N acts on the body shown during only the first 6 m. of its motion starting from rest. If u = 0.20, find the velocity of the body after it has moved a total distance of 9m. a) 3.93 m/sec² b) 4.73 m/sec² c) 2.32 m/sec² d) 3.11 m/sec² Solution: [positive work->negative work = 1/2 (W/g)(V2V,3 Answer. V2 = 3.93m/sec²
