A 6.3 kg body is initially moving northward at 19.5 m/s. Then a force of 8 N, toward the east, acts on it for 1.9 s. (a) At the end of the 1.9 s, what is the body's final velocity? (b) What is the change in momentum during the 1.9 s? (a) v= m/s at O north of east (b) Ap = kg m/s (select) (select) northeast east north
