to find angular momentum when the object is halfway back to the ground, should i use the velocity at that point? and to find r, would i use the hypotenuse of the height of the object and the distance the object is from P?
A cylinder of mass M and radius R smoothly rolls from rest along a ramp and onto a final horizontal section. From there it rolls off the ramp and lands on a floor at a horizontal distance of d = 0.505 m from the end of the ramp. The initial height of the cylinder is H = 0.98 m; the height h of...
A 0.380 kg ball is shot directly upward with an initial speed of 38.5 m/s. What is its angular momentum about point P, at a horizontal distance of 1.85 m from the launch point, when the ball is at its max height? Halfway back to the ground? What is the torque on the ball about point P due to...
