Awave on a string is described by y(x, t) : 15.0 sin( ncls - where x and y are in centimeters and / is in seconds. (a) what is the transverse speed for a point on the string at x : 6.00 cm when t - 0.250 s? (b) what is the maximum transverse speed of any point on the string? (c) what is the magnitude of the transverse acceleration for a poi

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
