For each statement, pick the phrase that will make it true. K.g., if A makes the first statement true, and B makes the rest true, enter ABBB, Select from: A) the same B) a greater C) a smaller i. A small Hot-wheels car and a marble roll, from rest and without sipping, down on incline. Neglecting frictional losses, the marble takes amount of time to reach the bottom of the incline, compared to the car. i. A block slides down a frictionless incline and a sphere rolls without sipping down on incline of the some angle, theta. The block and the sphere have the some moss; they both start from rest. The block takes amount of time to reach the bottom of the incline, compared to the sphere. ii. Five round bodies of the some radius and moss ore stored from rest together and roll, without slipping, down on inclined plane. The bodies are a solid sphere, a hollow sphere, a hollow cylinder, a cylindrical can full of juice, and a sold cylinder. The solid sphere takes time compared to the hollow sphere to reach the bottom of the incline. iv. Two identical bolls ore released from rest and roll without stopping to the bottom of their respective inclined planes. They are released from the some vertical height; incline 2 is much steeper then incline 1, Boil 1 takes amount of time to reach the bottom, compared to ball 2. Answer:
Solution
Factors to be cosidered here are the weight of the object, angle of steepness and friction. But it is mentioned that friction can be neglected.
1. Smaller amount of time because the rotatinal inertia for solid cylinder is less than that of hot wheel car.
3. Solid sphere will reach first since it has least rotational inertia.
2. Sphere will reach first because it has both rotational and linear acceleration.
4. Ball 1 takes more amount of time
