How My Work (Optional)? Submit Answer 32 - Ф Fx(N) 2 3 4 5 от 6 t(s) An object with a mass of 14.8 kg experiences the force described by the graph above. For this problem the motion is in 1-dimension and positive values for force, impulse, velocity, and momentum correspond to the +x direction, or "to the right." (a) Find the magnitude of the impulse of the force imparted on the object. magnitude of impulse = kg.m/s (or N⚫s) (b) For what length of time does the object interact with the force? time of contact = S (c) If the object was originally at rest, what is the momentum, P final, after the object experiences the force? Remember that AP = Pfinal - Pinitial magnitude of Pfinal direction of Pfinal = ○ to the right to the left = kg.m/s (d) What is the velocity of the object after it experiences the force? magnitude of Ufinal: direction of Ufinal = ○ to the right = m/s to the left (e) If the object was originally traveling to the left at a speed of 0.45 m/s, what is the momentum, Pfinal, after the object experiences the force? magnitude of Pfinal = direction of P final = to the right ○ to the left kg.m/s
