Afirefighter directs a stream of water travelling at 35.0 m/s from a fire hose at angle of 32.0° above the horizontal towards a building. the end of the hose is 1.00 m above the level ground. the water hits the building at a height of 17.6 m from the ground as shown in the diagram below. assuming that there is negligible air resistance and that the water is projectile, determine how far the firefighter is from the base of the building.

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.
