Transcribed Image Text:Learning Goal:
To use the principle of linear impulse to
determine the change in velocity of a box
subject to multiple forces.
The block shown in (Figure 1) has mass m =
40 kg and is subjected to forces F₁ = 230 N
at an angle = 20° below the horizontal
and F2 = 70 N. The coefficient of kinetic
friction between the box and the surface is
k=0.11. What is the velocity of the box
after 15 s if it starts at rest?
