Unformatted text preview: The negative sign indicates the downward direction, so the speed is 37.0 m/s . ( c ) The total distance includes the distance up to the maximum height, down to the top of the cliff, and down to the bottom. We find the maximum height from v 2 = v 2 + 2 ah ; 0 = (10.0 m/s) 2 + 2( 9.80 m/s 2 ) h , which gives h = 5.10 m. The total distance traveled is d = 5.10 m + 5.10 m + 65.0 m = 75.2 m . 84. The instantaneous velocity is the slope of the x vs. t graph: Page * 10 20 30 40 50 t (s) 10 20 x (m) 85. We use a coordinate system with the origin where the Page *...
