The lowest note on a grand piano has a frequency of 27.5 Hz. The entire string is 2.00 m long and has a mass of 440g . The vibrating section of the string is 1.75m long.
What tension is needed to tune this string properly?
A baseball is hit so that it travels straight upward after being struck by the bat. A fan observes that it takes 2.80 s for the ball to reach its maximum height. (a) Find the ball's initial velocity. m/s upward (b) Find the height it reaches.
Let the building is 50 m tall, the initial horizontal velocity is 9.0 m/s, and the initial vertical velocity is 12.0 m/s. select your coordinates such that the positive y-axis is upward, and the x-axis is to the right, and the origin is at the poi..
A wave on a string is described by the relation y = A sin(47t - 0.023x), where t is measured in seconds and x in meters, with A = 0.18 m, Find the frequency of the wave
what is the ball's speed immediately after the collision?
