Phoebe's insulated foam cup is filled with 149.0 g of coffee (mostly water - c = 4.2 J/g·°C) that is too hot to drink, so she adds 11.0 g of milk at 9.0 °C. If the coffee has an initial temperature of 65.0 °C and the specific heat of milk is 3.8 J/g·°C, how hot is the coffee after the milk is added? (Assume that no heat leaks out through the cup.)

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.
