Instructions for questions 3-5 You have a cylinder. You don't know what its internal structure looks like. but you plan to roll it down a ramp, as in this week's procedure. The ramp is \( 1 \mathrm{~m} \) long, and is elevated at an angle of \( 15^{\circ} \). The mass of the cylinder is \( 450 \mathrm{~g} \) and its diameter is \( 2.1 \mathrm{~cm} \). Answer the following questions regarding this situation. 3 0.2 points You set the cylinder and hold it at rest at the top of the ramp. How much total energy (in J) does the block have at the top of the ramp? 4 0.2 points After you release the cylinder, it rolls down the ramp without slipping. gaining speed. How much total energy (in J) does the block have at the bottom of the ramp? \( 5.02 \) points [Caution Tricky] If the velocity of the cylinder is \( 1.75 \mathrm{~m} / \mathrm{s} \) at the bottom of the ramp. what is the value of \( k \) (see equation 3 ) for this unusual cylinder (in SI units)? Express your answer as a decimal (i.e. \( 1 / 4=0.25 \) ).
