The assembly starts from rest and reaches an an-
gular speed of 150 rev/min under the action of a
20-N force T applied to the string for t seconds. De
termine t. Neglect friction and all masses except
those of the four 3-kg spheres, which may be
treated as particles.

a car has a constant acceleration , start from rest untill vf=22 m/s in 9 s , if the tire radius is 58 cm , calculate : a) The number of possible turns of the wheels during normal vehicle movement assuming no slip . b) the speed of wheels turn in ( rev/s )
A simple pendulum is given an initial tangential velocity such that it swings in acomplete circle around its fulcrum. Assume:● The string is 32 meters long● The bob has mass M Determine: (A) The minimum velocity atthe top ofthe loop. Now assume the mass passesthrough the top of the loop with theminimum found in part (a), above; Determine: (B) the velocity at an angle of 30 degrees from the vertical(i.e.: at 30 degrees up from a position fully at the bottom of the loop).
A rocket of mass 10^5 kg is launched fromthe surface of the Earth. This is a sketch of the rocket as it’s still in Earth’s atmo-sphere. The rocket is undergoing an accel-eration of 3 m/s^2 upward. There is a forceexerted on the rocket from the thrust of itsengines labeled here as FEngine (you can useFE for short). The rocket is still close to theEarth’s surface, so it is subject to Earth’s gravity, and it is also subject to a substan-tial air resistance force. a. Draw a complete free body diagram of the rocket with all forces acting on it, clearlyindicating which direction each forces act. b. What is the weight of the rocket, and what is the net force on the rocket? c. If the force the engine is exerting is FE = 1.8×10^6 N, what is the magnitude of the forceof air resistance? d. What is the work done by the engine as the rocket rises 150 m?
Three uniform spheresare fixed at the positions shown inFig. . (a) What are the magnitudeand direction of the force ona 0.0150 kg particle placed at P?(b) If the spheres are in deep outerspace and a 0.0150 kg particle isreleased from rest 300 m from theorigin along a line 45 below the-x-axis, what will the particle’sspeed be when it reaches the origin?
