For rolling a ball , there should be friction between ball and surface .
Hence I think last option is correct .
Rolling a ball requires which of the following: 1. centripital acceleration 2. inear velocity 3. constant...
A soccer ball is rolling with a constant acceleration of -1.5 m/s2. At ti = 0 s, the ball has an instantaneous velocity of 14 m/s. After 3s of rolling, what would be the velocity of the ball (in m/s)?
5) An object is moving to the left at constant velocity. A constant force to the left is now applied to the object. Which of the following is correct? A) The object continues to move to the left, and its speed increases. B) The object continues to move to the left with a constant speed. C) The object continues to move to the left, and its speed decreases. D) The object immediately stops and then begins moving to the right...
Group Activity: Ball rolling down ramp and off cliff As shown in the figure below, a hollow ball with a mass m 5.00 kg and radius r -30.0cm starts from rest and rolls a distance of 1.2 m down a 30° ramp, before reaching a flat section at the bottom of the ramp. The ball then rolls along the flat section for 1.0 m before rolling off a 2.5 m-high cliff. The ball lands a distance d from the bottom...
Q1-6: A ball is rolling on a surface for which f(x) = 2x² - 4x + 5. The ball passes point A (xo = 4 m ) with the speed v = 5 m/s, which increases at the rate of 4 m/s . Find (a) the normal and tangential components of the acceleration of the ball as it passes point A, (b) the angle between the acceleration and velocity vectors at A. y = f(x) Xo

FROBLEMS University Physics I Homework 2-1D Kinematics 1) Can an object with constant acceleration reverse its direction of movement? 2) Under what conditions is the average velocity of an object equal to the instantaneous velocity? From the top of a tall building, you throw a ball straight up with a speed vo and another ball straight down at the same time with the same speed (ignore air resistance) a) Which ball has the greater speed when it reaches the ground?...
A camival ride is designed to allow the general public to experience high acceleration motion. The ride rotates about Point o in a horizontal circle such that the rider has a speed Vo The nicer reclines on a platform A which rides on rollers such that friction is negligible A mechanical stop prevents the platform from rolling down the incine. The camivalnde is modified so that 80 kg nders can move up and down the inclined wall as the speed...
A spherical bowling ball with mass m = 3.8 kg and radius R = 0.106 m is thrown down the lane with an initial speed of v = 8 m/s. The coefficient of kinetic friction between the sliding ball and the ground is p = 0.33. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down...
please explain III Which of the following is the correct graphical representation for C-(A-B)? (Symbols in bold type are vectors) IIII] When a ball is thrown vertically up with some initial speed it slows down as it moves up reaches a certain maximum height, and then falls straight down. Assume no air friction. During the trajectory of the ball in the air, which one of the following is true? lal The acceleration and velocity of the ball both increase on...
