question 14

Multiple Choice

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) \(9.55 \times 10 ^ { 3 } \mathrm {~kg} \cdot \mathrm { m } / \mathrm { s }\)
