Find the impulse due to the force vecF=ahati+bthatj, where a=2N and b=

1.	Find the impulse due to the force vecF=ahati+bthatj, where a=2N and b=4Ns^(-1) if this force acts from t_(i)" to "t_(f)=0.3s
Answer» SOLUTION :`J=int_(t_(i))^(t_(F))vecF.dt=int_(0)^(0.3)(ahati+bthatj)dt` `J=aint_(0)^(0.3)dt hati+bint_(0)^(0.3)tdthatj=a[t]_(0)^(0.3)hati+b[(t^(2))/(2)]_(0)^(0.3)HATJ` `=2xx0.3xxhati+4xx((0.3)^(2))/(2)xxhatj=0.6hati+0.18hatj" NSec"`
