Find the thrust of the wall, and the force of the point on the ground.Ī large swinging ball is used to drive a horizontal iron spike into a vertical wall. A ball has fallen to the street below, and a passerbyĪ uniform ladder 16 m long weighing 80 N leans against a smooth vertical wall, making 30 degree with the wall. The vertical wall of the building is h = 7.30 m high, to form a 1.5-m-high railing around the playground. the acceleration system isĪ playground is on the flat roof of a city school, 5.8 m above the street below (see figure). Two bodies of mass 3kg and 4kg are suspended at the ends of massless string passing over a frictionless pulley. A fourth particle D, with mass 4.00mA, is to be placed near the other three Particle A has mass mA = 4 g, particle B has mass 2.00mA, and particle C has mass 3.00mA. In the figure, three point particles are fixed in place in an xy plane. the force acting on the particle is a/x^2 - b the point of equilibrium of the particle is 1.10 m a) The particle's motion is restricted to the region x>0. What is the magnitude of the impulse delivered to the particle?Ī particle of mass 1.1 kg moves under the influence of a potential U(x) = a/x + bx (a=3 and b=2.5). The particle rebounds with a speed of 3.0 m/s. What (a) x coordinateĪ 4.0-kg particle is moving horizontally with a speed of 5.0 m/s when it strikes a vertical wall. A fourth particle D, with mass 4.00mA, is to be placed near the other three particles.
Particle A has mass mA = 3 g, particle B has mass 2.00mA, and particle C has mass 3.00mA. Three point particles are fixed in place in an xy plane. A mass 20kg is hung from a point on the ladder at a distance 2m from B. The angle made by theĪ uniform ladder AB of length 6m and mass 40kg rests in a vertical plane with his end B on smooth horizontal ground and the end A against a smooth vertical wall. The other end of the string is attached to a fixed point O and the particle moves in a vertical circle about the fixed point. In the absence of air friction, the system oscillates by swinging back andĪ pendulum consist of a particle P of mass m, attached to one end of a model string of length l=2.85m. The string, with its top end fixed, has negligible mass and does not stretch. Find theĪ simple pendulum, consists of an object suspended by a string. A particle of mass 4kg is suspended from a point A on a vertical wall by means of a light inextensible string of length 130cm.A horizontal force P, is applied to the particle so thatĪ particle of mass 4kg is suspended from a point A on a vertical wall by means of a light inextensible string of length 130cm.A horizontal force P, is applied to the particle so that it is held in equilibrium a distance of 50cm from the wall.
