If the man pulls the strap with constant acceleration during a short time interval Δt, calculate the force (in Newtons) that he must exert in spinning up the disc. These are the numbers. Strap's final speed = v = 1.9 m/s. The disc's radius is R = 0.4 m The disc's mass is M = 2.4 kg The short time interval is Δt = 0.3 s The disc initially is non-rotating.
