Number 6 and 7 show all work please

6) A 0.315-kg particle moves from an initial position , = 2.00 i - 1.00 j + 3.00 k m to a final position 72 = 4.00 i - 3.00 j - 1.00 k m while a force F = 2.001 - 3.00 / + 1.00 k N acts on it. What is the work done by the force on the particle? 7) Compute the kinetic energy for each of the cases below. Through what distance would a 800-N force have to act to stop each object? (a) A 150-g baseball moving at 40 m/s; (b) a 13-g bullet from a rifle moving at 635 m/s; (c) a 1500-kg Corvette moving at 250 km/h; (d) a 1.8x10'-kg Concorde airliner moving at 2240 km/h
