Awave has a speed of 50 m/s and a frequency of 10 hz. calculate its wavelength.

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m. the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?

When solid surfaces slide over each other the kind of friction that occurs is called friction
