The initial velcoity of particle vec(u)=4 hati + 3hatj. It is moving with uniform acceleration vec(a) = 0.4 hati+0.3 hatj . Its velocity after 10 seconds is : |
|
Answer» 3 UNITS `vec(V)=vec(u) +vec(a)t=(4hati+3hatj)+10(0.4hati+0.3hatj)` `=(4hati+3hatj)+(4hati+3hatj)` `vec(V)=(8hati+6hatj)` `|V|=sqrt((8)^(2)+(6)^(@))=10` units |
