A particle of mass m=5 kg slides on a smooth, level surface. A force F=5 N is applied to the particle so that as the particle moves on the surface; the force always acts towards the fixed point O. Initially, the particle is at P with coordinates x=fo=1 m, y=0 and has a velocity vo 2 m/s in the y direction, as shown in the figure. The subsequent motion of the particle is such that it moves further away from O until it reaches a maximum distance from O at Q. F V? P 0 F Calculate the following: (a) the angular momentum Ho of the particle about O in its initial position at P. V A (b) the distance r, between O and Q, if the magnitude of the particle's velocity at Q is measured as v? = 0.73 m/s. v (c) the work AU done on the particle by the force Fas the particle moves from position P to position Q. (a) 2 kg m^2/s (a) 5 kg m^2/s (a) 10 kg m^2/s (a) 20 kg m^2/s (b) 2.73 m. (b) 5.46 m (b) 6.83 m (b) 13.7 m (c)-8.7 J (c) 8.7 J (c) -23.8 J (c) 23.8 J be ne er qu
