... 15. REASONING AND SOLUTION The amount of force F needed to stretch a rod is given by Equation 10.17: F Y( L / L0 )A , where A is the cross-sectional area of the rod, L0 is the original length, L is the change in length, and Y is Young's modulus of the material. Since the cylinders are made of t ...

... The free-body diagram has not changed, nor has the expression of Newton’s Second Law. You might think that because the goat is moving, we’re now talking about kinetic friction, but as long as the goat’s hooves do not slip against the rock face, it’s still static friction. As for the direction of the ...

... kicks it in the exact opposite direction at 22 m/s with an average force of 1200 N. How long are his foot and the ball in contact? answer: We’ll use Fnet t = p. Since the ball changes direction, p = m v = m (vf - v0) = 1.3 [22 - (-13)] = (1.3 kg) (35 m/s) = 45.5 kg · m /s. Thus, t = 45.5 / 1200 = ...
