Transverse waves on a string have wave speed amplitude 0.0700 m, and wavelength 0.320 m. the waves travel in the and at the end of the string has its maximum upward displacement. (a) find the frequency, period, and wave number of these waves. (b) write a wave function describing the wave. (c) find the transverse displacement of a particle at at time (d) how much time must elapse from the instant in part (c) until the particle at next has maximum upward displacement?

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?
