At a local playground, a child on a swing has a speed of 3.4 m/s when the swing is at its lowest point. a.) To what maximum vertical height (above the bottom of the swing) does the child rise, assuming he sits still and "coasts"? b.) Reanswer part a, with the initial speed of the child being...

A kayaker paddles with a power output of 53.0 W to maintain a steady speed of 1.50 m/s. Calculate the resistive force exerted by the water on the kayak. If the kayaker increases her power output by a factor of 2.5, and the resistive force due to the water remains the same, by what factor does...
