If you push a particle of mass M inthe direction in which it is already moving, you expect theparticle's speed to increase. If you push with a constant forceF, then the particle will accelerate with accelerationa=F/M (from Newton's 2nd law).
A. Enter a one- or two-word answer that correctly completes thefollowing statement.
If the force is applied for a fixed interval of time t, then the of the particle will increase by an amountat.
B. Enter a one- or two-word answer that correctly completes thefollowing statement.
If the force is applied over a given distance D, along the path of the particle, thenthe of the particle will increase byFD.
C. If the initial kinetic energy of the particle isK1, and its final kinetic energy isKf, express Kfin terms of K1 and thework W done on theparticle.
D. Now, consider whether the following statements are true orfalse:
1. The dot product assures that the integrand is alwaysnonnegative.
2. The dot produc indicates that only the component of theforce perpendicular to the path contributes to theintegral.
3. The dot product indicates that only the component of theforce parallel to the path contributes to the integral.
E. Assume that the particle has initial speedv1. Find its final kinetic energy Kf in terms ofv1, M, F, andD.
F. What is the final speed of the particle?
