3. You are out hiking and come across a calm river. You are curious how wide the river is and come up with a clever way of determining it. Someone has left their kayak on your side of the river but the paddle is nowhere to be found. So, you put the kayak in the water pointed at the opposite bank of the river. You then get a running start and jump onto the kayak. As you land on the kayak you start a timer on your cell phone. You and the kayak float across the river and reach the other side. At that moment you stop the timer. You then repeat this four more times recording your data in a table (shown). You estimate that you have a mass of 70.0kg, the kayak has a mass of 20.0kg, and that you were running at about 3.00m/s when you jumped onto the kayak. a. Determine the width of the river. Include uncertainty. Trial Time interval (s) 1 8.5 2 8.2 3 9.1 4 8.9 8.2 S b. Describe one questionable assumption that you made in your method. Will this cause your answer to part a. to be larger, smaller, or randomly different than the actual width of the river? 3. You are out hiking and come across a calm river.
