On a smooth surface, a 0.140-kg toy car 1 at the velocity of 5.0 m/s collides
elastically with another 0.100-kg toy car 2 with a velocity of 3.0 m/s. The
velocities of the two toy cars are in the same direction. After the collision, toy
cars 1 and 2 keep moving in the same direction with toy car 1 having a velocity of
2.8 m/s. What is the velocity of toy car 2 after the collision? Show the steps on
how you arrived at your final answer. Are the momentum and kinetic energy of
the system conserved in this collision? Explain.

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
