- Please Show step by step solutionWhat the best answer4. A cylinder [Im = MR/2] starts from rest at height H at the upper end of the track shown, and rolls without slipping until H leaving the horizontal portion of track at height h as shown. (a) What is the cylinder's linear speed as it leaves the track? (b) How does its kinetic energy associated with this speed compare to its change in gravitational potential energy from H to h? (c) How far to the right does the cylinder land from the end of the track?
- Question is on the picturethis is the introductory question to our new chapter and my professor didn’t list any formulas to use for certain question types and i’m just really stuck on this oneA thin cylindrical ring starts from rest at a height h1 = 98 m. The ring has a radius R = 34 cm and a mass M = 4 kg. Part (a) Write an expression for the ring's initial energy at point 1, assuming that the gravitational potential energy at point 3 is zero. Part (b) If the ring rolls (without slipping) all the way to point 2, what is the ring's energy at point 2 in terms of h2 and v2? Part (c) Given h2 = 32 m, what is the velocity of the ring at point 2 in m/s? Part (d) What is the ring's rotational velocity in rad/s? Part (e) After passing point 2 the hill becomes frictionless and the ring's rotational velocity remains constant. What is the linear velocity of the ring at point 3 in m/s?
- Please answer Mcq 5, 6, v and vii.The figure shows a ball with mass m = 0.69 kg attached to the end of a thin rod with length L = 0.99 m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. (a) What initial speed must be given the ball so that it reaches the vertically upward position with zero speed? What then is its speed at (b) the lowest point and (c) the point on the right at which the ball is level with the initial point? (d) If the ball's mass were doubled, what would the answer to (a) be?A hollow sphere rolls without slipping down a ramp that is 3.5 m long. the ramp is inclined at an angle of 20˚ with the horizontal. Use the conservation of energy to find the speed of the sphere at the bottom of the slope if it starts from rest. ( I= 2/3 m R2 )
