A 600-Kg Car Makes A $90 ^ { \circ }$ Turn Its Speed Before the Turn Is 21

A 600-kg car makes a $90 ^ { \circ }$ turn. Its speed before the turn is 21.0 m/s and after the turn it is 24.0 m/s. What is the magnitude of the change in the car's momentum during the turn?

A) $22.2 \times 10 ^ { 3 } \mathrm {~kg} \cdot \mathrm { m } / \mathrm { s }$
B) $12.0 \times 10 ^ { 3 } \mathrm {~kg} \cdot \mathrm { m } / \mathrm { s }$
C) $19.1 \times 10 ^ { 3 } \mathrm {~kg} \cdot \mathrm { m } / \mathrm { s }$
D) $10.2 \times 10 ^ { 3 } \mathrm {~kg} \cdot \mathrm { m } / \mathrm { s }$
E) $9.55 \times 10 ^ { 3 } \mathrm {~kg} \cdot \mathrm { m } / \mathrm { s }$
