One of the explorers is able to jump a maximum distance of 16.5 m with an initial speed of 2.20 m/s. Find the gravitational acceleration on the surface of the exoplanet. Assume the planet has a negligible atmosphere. (Enter the magnitude in m/sz.) -: Note that the given distance is the maximum horizontal range, not the maximum vertical height, for the given initial speed. m/sz Need Help? 2.

Water owing at 1.85 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 3.00 m high, and from there it will fall into a pool (see the gure below). (D (a) The architect has asked you to determine if the space behind the waterfall will be wide enough for a pedestrian walkway. (Enter the maximum width, in meters, of a walkway behind the waterfall.) :lm (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. She asks you to design and build the model, with the important question being: how fast (in m/s) should the water flow in the channel in the model? :1 m/s Need Help
