A Constant Force F Is Applied to a Body of Mass

question 25

Multiple Choice

A constant force F is applied to a body of mass m that initially is headed east at velocity v0 until its velocity becomes -v0. The total time of travel is 2t. The total distance the body travels in that time is:

• A) \(\frac{1}{2} \frac{F}{m} t^{2}\) .
• B) \(\frac{F}{m} t^{2}\) .
• C) \(v_{0} t-\frac{1}{2} \frac{F}{m} t^{2}\) .
• D) \(v_{0} t+\frac{1}{2} \frac{F}{m} t^{2}\) .
• E) \(2\left(v_{0} t+\frac{1}{2} \frac{F}{m} t^{2}\right)\) .
