A 20-Kg Particle Has an Initial Velocity Of Of $( 5 \tilde { \mathbf { i } } - 4 \tilde { \mathbf { j } } )$

Multiple Choice

A 2.0-kg particle has an initial velocity of $( 5 \tilde { \mathbf { i } } - 4 \tilde { \mathbf { j } } )$ m/s.Some time later,its velocity is $7 \tilde { \mathbf { i } } + 3 \tilde { \mathbf { j } }$ m/s.How much work was done by the resultant force during this time interval,assuming no energy is lost in the process?

A) 17 J
B) 49 J
C) 19 J
D) 53 J
E) 27 J
