Find the Work Done by F Over the Curve in the Direction

Question 210

Multiple Choice

Find the work done by F over the curve in the direction of increasing t.
- F=ti+12j+k;C:r(t) =e2ti+e2tj+(7t2+t) k,1t1\mathbf { F } = \mathrm { ti } + \frac { 1 } { 2 } \mathrm { j } + \mathbf { k } ; \mathrm { C } : \mathbf { r } ( \mathrm { t } ) = \mathrm { e } ^ { 2 } \mathrm { t } _ { \mathbf { i } } + \mathrm { e } ^ { 2 } \mathrm { t } \mathbf { j } + \left( - 7 \mathrm { t } ^ { 2 } + \mathrm { t } \right) \mathbf { k } , - 1 \leq \mathrm { t } \leq 1


A) W=e2+e212W = e ^ { 2 } + e ^ { - 2 } - 12
B) W=e2+e2+2\mathrm { W } = \mathrm { e } ^ { 2 } + \mathrm { e } ^ { - 2 } + 2
C) W=12W = - 12
D) W=2W = 2
