When is the displacement in simple harmonic motion maximum? If the length of a simple pendulum with a period T is reduced to half of its original value, what would be its new period (in terms of T)? Which one is more elastic? Rubber or steel? Explain. An 80-cm-long, 1.0-mm-diameter steel guitar string must be tightened to a tension of 2000 N by turning the tuning screws. By how much is the string stretched? Young’s Modulus of elasticity for steel...
A tennis player serves a tennis ball such that it is moving horizontally when it leaves the racquet. When the ball travels a horizontal distance of 16 m, it has dropped 59 cm from its original height when it left the racquet. What was the initial speed, in m/s, of the tennis ball? (Neglect air resistance.)
