After a snowstorm, a boy and a girl decide to have a snowball fight. the girl uses a large slingshot to shoot snowballs at the boy. assume that the girl fires each snowball at an angle θ from the ground and that the snowballs travel with an initial velocity of vo. 1. in terms of the initial velocity, vo, and the launch angle θ, and g, for what amount of time, t, will a snowball travel before it reaches its maximum height above the ground? (hint: recall that vf = 0m/s when an object reaches its maximum height, this is because it is slowing down on the way up, and at the moment it changes directions, it has a velocity of 0m/s. answer should be t= (an expression with vo and θ and g). 2. what is the maximum height, h, above the ground that a snowball reaches after it has been launched? 3. what is the horizontal distance, x, the snowball has traveled when it reaches its maximum height? 4. the range, r, is the horizontal distance traveled in twice the time it takes for an object to reach its maximum height. using your answers from items 1 and 3, write an expression for the range in terms of vo and g. if you can, could you explain the answer too? you

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
