You are standing at position A and your friend at position B on a lake shore as shown in (Figure 1). Suppose that h = 3.0 m, l = 4.0 m. Someone throws a ball so that it lands on the lake surface at point S. The ball produces a circular pulse that propagates along the water surface with a speed of 0.30 m/s.
Determine the ratio of the pulse amplitudes observed by you and your friend, assuming there is no damping.

ReviewI ConstantsI Periodic Table A combination work of art/musical instrument is illustrated. (Figure 1) Six pieces of identical piano wire (cut to different lengths) are hung from the same support, and masses are hung from the free end of each wire. Each wire is 1, 2, or 3 units long, and each supports 1, 2, or 4 units of mass. The mass of each wire is negligible compared to the total mass hanging from it. When a strong breeze blows,...

You and your friend are standing on level ground 25.0 m apart. They are getting ready to test their tennis ball cannon, which is positioned next to your friend. The cannon is aimed upward at an angle of 50° with respect to the ground and has an adjustable launch speed. a) The cannon fires. Draw a motion diagram for the tennis ball while it is in flight (include several “v” arrows and one “delta v” arrow). b) What launch speed...

PLEASE ANSWER ALL PARTS, THANK YOU !!!!! You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass of is 84.0 kg, and the mass of the sled when empty is 11.0 kg. (a) From shore, someone throws a baseball of mass 0.11 kg to you, and you catch it; the horizontal component of the ball’s velocity is 25.2 m/s. What will be the sled’s (and your) speed with respect to...

You are standing on a cliff overlooking a lake and decide to throw a tennis ball to your friends in the water below. You throw the tennis ball with a velocity of 20.5 m/s at an angle of 39.5° above the horizontal. When the tennis ball leaves your hand it is 13.5 m above the water. How far does the tennis ball travel horizontally before it hits the water? In your calculations, neglect any effects of air resistance.
