A block with a mass of 3.00 kg starts from rest at the top of a \( 29.5^{\circ} \) incline and slides 2.00 m down the incline in 1.45 s . (a) What is the magnitude of the acceleration of the block (in \( \mathrm{m} / \mathrm{s}^{2} \) )? (b) What is the frictional force (in N ) acting on the block? (Enter the magnitude.) (c) What is the coefficient of kinetic friction between the block and the incline? (d) What is the speed of the block (in \( \mathrm{m} / \mathrm{s} \) ) after it has slid 2.00 m ? (d) \( \mathrm{m} / \mathrm{s} \)
