An object is thrown vertically upward from the ground with an initial velocity of v0 (unknown). The figure shows the y-position of the object as a function of time t. y1 represents the maximum height. Given that t2= s and y2= m, what is the initial velocity v0 in m/s?

A river flows with a velocity represented by vector A, where 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= 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.

You throw two objects, A and B, vertically upward at the same time from y=0. The initial velocities are v0A = m/s and 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).
