Doesn't the velocity increase as when a ball falls towards the ground it generally speeds up. The graph was a displacement time graph. Then it said air resistance was negligible which would mean the ball would accelerate constantly at 9.81ms^-2 so velocity would increase as it's accelerating? Thank you for all your answers btw, they're very helpful
velocity is decreasing as the gradient is getting more negative but magnitude of velocity increasing and it comes to instanreous rest then rebounds (so vpositive velocity but negative gradient e.g. negative acceleration)
I thought that since the question asked about the rotation work done, so it couldn't be 0 since it said it rotated once. Idk if i'm remembering this question correctly. so I did circumference x force x 2?

Velocity decreases as gradient was negative and displacement is negative but the magnitude of velocity was increasing E. G. Speed
