Question

The next two questions (24 and 25) pertain to the following graph, which illustrates the net force acting on a 250kg object initially moving to the right (the x direction) at 5m/s F: (N 1500 1000 500 -5002 48 10 -1000 24.) 12 pointsl What is the impulse experienced by the object due to the net force acting on it? a.)-4000N-s b.)-2000Ns C.) ON-S d.) 2000N-s e.) 4000N s 25.) 13 pointsl What is the object's velocity after the net force has acted on it? a.) -5.0m/s c.)-2.5m/s d.) 10.0m/s e.) -11.0m/s

Explanation / Answer

24. Impulse = Fxt area under curve
   =-4000 N-s

25. mxVf= mxVi + Impulse
   250 x Vf = 250 x5 - 4000 = -2750

Vf =-11 m/s
