What impulse does the force shown in FIGURE EX11.3 exert on a 250 g particle?

Video transcript

Hi, everyone in this practice problem, we will be asked to find the impulse on the object or will have a 300 g object experiencing a force that varies with time shown in the F versus T graph in the figure. So in the figure, it is given that we will have FX on the Y axis in Newton and T in the X axis in seconds. And the, the shape of our force will be in a triangle with a width or base of 12 seconds and a height of 15 Newton. The options for the impulse on the object are a 19 Newton seconds. B 100 and 20 Newton seconds, C 18 Newton seconds and D 100 and 50 Newton seconds. So to find the impulse on the object, we need to find the area under the F versus the graph. So area, Well, actually equals two, the impulse where we, where when we'll have an F versus the graph. So in this case, then impulse will equals to the area of the triangle which is going to be half multiplied by the base multiplied by the height. So the base is going to be 12 seconds And the height is going to be 15 Newton. So in this case, our impulse Will then be n seconds. So the impulse of the on the impulse on the object is going to be 19 new 10 seconds, which is going to correspond to option a. So option a is going to be the answer to this practice problem.
