Asmall dense ball with mass 1.5 kg is thrown with initial velocity < 3, 6, 0 > m/s at time t = 0 from a location we choose to call the origin (< 0, 0, 0 > m). air resistance is negligible.
(a) when the ball reaches its maximum height, what is its velocity? it may to make a simple diagram.
(b) when the ball reaches its maximum height, what is t? you know how upsilon_y depends on t and you know the initial and final velocities.
(c) at a later time the ball's height y has returned to zero, which means that the arithmetic average value of upsilon_y from t - 0 to this time is zero. at this instant, what is the time t?
(d) at the time calculated in part (c), when the ball's height y returns to zero, what is x? (this is called the "range" of the trajectory.)
(e) what was the angle to the x-axis of the velocity at the time calculated in part (c), when the ball's height y returned to zero?

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
