Three forces act on a particle that moves with unchanging velocity   v→=(2.4 m/s)î+(-7.2 m/s)ĵ. Two of the forces are    F→1=(2.7 N)î+(3.3 N)ĵ+(-1.1 N)k̂ and    F→2=(-4.0 N)î+(4.4 N)ĵ+(-2.4 N)k̂. What is the third force?


Expert Answer

Step 1

As the particle moves with unchanging velocity, the net acceleration is zero. Hence, the total force is also zero in accordance with Newton’s 2nd law. Therefore,

Step 2
