An object is thrown vertically upward from a height of y1= [y1] m with an initial velocity of v0 = [v0] m/s. The position versus time graph is shown in the figure.  What is time t2? Express your answer in seconds (s).

You throw two objects, A and B, vertically upward at the same time from y=0. The initial velocities are v0A = [v0A] m/s and v0B = [v0B] m/s. The blue curve in the figure shows the y-position as a function of time t for object A. At time t = t1, object A reaches its maximum height y2. What will be the position of object B at time t = t1? Provide your answer in meters (m). 

A river flows with a velocity represented by vector A, where A= [A] m/s, as shown in the figure. You steer a motorboat across the river; your velocity relative to the water is represented by vector B, where B= [B] m/s, as shown in the figure. What is the speed of the motorboat relative to a person standing on the riverbank?  Express your answer in m/s.
