The problem I am facing is that on a straight line friction is there and I can't balance it. Using F=ma and T=Iw doesn't work.
But that's the problem I can't from those equationsCutter Ketch said:Knowing the mass of the ball and the coefficient of friction you know the force of friction, so you know what to put for Force and Torque. And don't forget that the ball is not constrained, so it gets torque and linear acceleration.

Rolling motion is a type of motion where an object moves along a surface while rotating about its own axis at the same time. This motion is commonly seen in objects such as wheels, balls, and cylinders.
Rolling motion and sliding motion are two different types of motion. In rolling motion, an object is in contact with a surface and rotates about its own axis while moving. In sliding motion, an object moves along a surface without any rotation.
The speed of rolling motion is affected by several factors, including the size and shape of the object, the surface it is rolling on, and the force applied to it. Other factors such as friction and air resistance can also impact the speed of rolling motion.
Yes, an object can have both rolling and sliding motion simultaneously. This is often seen in objects such as a ball rolling down a ramp, where it has both rolling motion along the ramp and sliding motion on the ground.
Rolling motion and rotational motion are closely related as both involve an object rotating about its own axis. However, rolling motion also includes translational motion along a surface, while rotational motion is purely rotational and does not involve any movement along a surface.
