1 Consider a ring, sphere and Solidey clinder all with the same mass. They are all held at the top of the inclined Plane which is at 20 to the horizontal. the top of the inclined Plane is 1m high. The shapes are released simultaneously and allowed to roll down the inclined plane. Assume the abjects roll with out slipping and that they are all made from the same material. Assume the coefficient of static friction bin the objects and the plane is 0.3. A) which shapes have the greater moment of inertia ? B) workout what order they would get to the bottom of the Slope! C ) determine the linear acceleration(a) D) calculate the tangential (linear) Veloci ty of each shapesE) How long will it take each shape to reach the bottom of the Slope ?I give you 100 coin please help me -

A force acts on a particle that has a mass of 1.5 kg. The force is related to the position x of the particle by the formula = 0.503 where if x is in meters and F is in newtons. (a) What are the SI units of C? (b) Find the work done by this force as the particle moves from = 3.0 to = 1.5 (c) At = 3.0, the force points opposite the direction of the particles velocity (speed is 12.0m/s). What is its speed at = 1.5? (d) Can you tell itsdirection of motion at using only the workkinetic energy theorem? Explain your calculations.
