Unformatted text preview: tendency to slip sideways on the banked track (where there is no reliance on friction). Then, find the minimum and maximum speeds, using a coefficient of static friction = 0.90. Determine the minimum velocity v which the wheel must have to just roll over the obstruction. The k G is k and it is assumed that the wheel rolls without slip. + A 3/206 The 450 kg ram of a pile driver falls 1.4 m from rest and strikes the top of a 240 kg pike embedded 0.9 m in the ground. Upon impact, the ram is seen to move with the pile with no appreciable rebound. Determine the velocity v of the ram and pile. 1.4 m 0.9 m The car starts at A and speeds up according to a t = 0.6 - 0.002 v 2 m/s 2 (v is the cars forward velocity) What are the velocity and acceleration of point the car when it reaches point B? 6/185. 1-oz bullet, v= 1600 ft/s, pendulum is 55 lbs, k O = 37 inches. h= 43 inches. Find w after bullet is embedded in the pendulum....
