Chapter 1.5, Problem 2dT
During a small time interval
In the space provided, draw an arrow to indicate the direction of the Instantaneous velocity vector of the car in the reference frame of the truck at instant 2. If the velocity is zero, state that explicitly.
Direction of instantaneous velocity of car in frame of truck at instant 2
Consider the following Statements:
Statement 1: “At: instant 2 the car and the truck arc side by side, so the velocity of the car in thetruck’s frame is zero at that instant.”
Statement 2: “Before instant 2, the truck is catching up to the car, so the truck sees the car as slowing down.”
Do you agree or disagree with each of the statements? Explain.

You decide to play a trick on your friend using a giant water balloon as shown in the figure below.The balloon is dropped (no initial velocity) from a height of 43.24 meters. At the exact moment you drop the balloon your friend throws a rock straight up to strike and burst the balloon before it lands. We will take the rock to be thrown with an initial velocity of 108 km/hr from an initial height of zero.Convert the rock's initial velocity into proper units. v0(rock) = meters/secondWrite an equation for the y of the balloon at any time. yballoon(t) =
