$($b$)$ In Experiment $1,$ the disk reaches the bottom of the ramp in time t$\_($disk $).$ In Experiment $2,$ the students release a block of ice from rest from the same height on a ramp inclined at the same angle $\backslash$theta $,$ as shown in Figure $3.$ Friction between the bloek and the ramp is negligible. The block reaches the bottom of the ramp in time t$\_($thock$-)$

Indicate whether t$\_($disk $)$ is greater than, less than, or equal to t$\_($block $).$

t$\_($disk $)>$t$\_($block $),$t$\_($disk $)=$t$\_($block $),$t$\_($disk $)$

Justify your reasoning.
