(a) What is the magnitude of the tangential acceleration of a bug on the rim of an 11.0-in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of $80.0\mathrm{rev}/\min$ in $4.60\mathrm{s}$ ? Your response is within $10\%$ of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. $\mathrm{m}/{\mathrm{s}}^2$ (b) When the disk is at its final speed, what is the magnitude of the tangential velocity of the bug? $\mathrm{m}/\mathrm{s}$ (c) One second after the bug starts from rest, what is the magnitude of its tangential acceleration? Your response differs from the correct answer by more than $100\%.\mathrm{m}/{\mathrm{s}}^2$ (d) One second after the bug starts from rest, what is the magnitude of its centripetal acceleration? $\mathrm{m}/{\mathrm{s}}^2$ (e) One second after the bug starts from rest, what is its total acceleration? (Take the positive direction to be in the direction of motion.) magnitude direction $\mathrm{m}/{\mathrm{s}}^2$ - from the radially inward direction
