일반물리학 1 — Force and Motion-I: Problem 31

31 A block is sent moving up a long, inclined, frictionless plane with an initial speed \( v_0 = 2.77 \text{ m/s} \). Assume that the angle of inclination is \( \theta = 28.0^\circ \). Find (a) the distance in which the block moves to its highest point, (b) the time the block takes to get there, and (c) its speed when it gets back to the bottom.
