A boy wants to use his slingshot to shoot water balloons into the air. His sling slingshot has a spring constant of 40 n/m and he pulls it back 1.5 m before releasing the water balloon and launching it into the air. If air resistance can be ignored and the water balloon has a mass of 1 kg, what is the approximate maximum height that the water balloon can reach? Recall that g= 9.8 m/s

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
