A 2.4 kg object is moving to the right in the positive x direction with a speed of 1.0 m/s .?
Object experiences the force shown in (Figure 1). What is the object's speed after the force ends?
What is the direction of the object’s velocity after the force ends?

An impulse will result in a change of momentum
As the mass does not change, the velocity must.
The impulse is the area under the curve
p = ½*2 = 1 N•s = 1 kg•m/s
As the impulse is positive, it increases the speed of the mass.
2.4(1) kg•m/s + 1 kg•m/s = 3.4 kg•m/s
3.4 kg•m/s / 2.4 kg = 1.4166666...
vf = 1.4 m/s
