Show that there is no acceptable solution to the time-inde, schrödinger equation for the infinite square well with e = 0 or e < 0. (tu special case of the general theorem in problem 2.2, but this time do it by solving the schrödinger equation, and showing that you cannot meet the bo conditions.) e do it by explicitly the boundary stationary state *problem 2.4 calculate (x), (x2), (p), (p2), 0x, and op, for the nth stationary of the infinite square well. check that the uncertainty principle is satisfied. wh state comes closest to the uncertainty limit?

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?
