The wheels of the 15Mg car generate the traction force F des

The wheels of the 1.5-Mg car generate the traction force F described by the graph shown here. If the care starts from rest, determine the linear impulse gained by the car within the first t=6 s. 30 kN.s 36 kN.s 6 kN.s 12 kN.s

Solution

Impulse = force * time = area of the diagram

Which is the (area of triangle of base 2 with height 6 ) + ( area of rectangle of base 4 with height 6) = 6+24 =30
