The 16-kg block A and the 21-kg cylinder B are connected by a light cable that passes over the 4-kg pulley (disk). If the system is released from rest, determine the velocity of the cylinder after it has descended 3 m. The coefficient of kinetic friction between block A and the horizontal plane is 0.3. Assume that the cable does not slip on the pulley. A 100 mm B

The 20-kg block A rests on the 55-kg plate B as shown Neglecting the mass of the rope and pulley, and using the coefficients of kinetic friction indicated, determine the time needed for block A to slide 0.5 m on the plate when the system is released from rest.

1) The 15-kg block A and 25-kg cylinder B are connected by the light cord that passes over a 5-kg pulley with Ia= 0.025 kg.m. If the system is released from rest, (with coefficient of friction between the block and ground of 0.3) calculate the angular acceleration of the pulley

1) The 15-kg block A and 25-kg cylinder B are connected by the light cord that passes over a 5-kg pulley with IG = 0.025 kg.m2. If the system is released from rest, (with coefficient of friction between the block and ground of 0.3) calculate the angular acceleration of the pulley

1) The 15-kg block A and 25-kg cylinder B are connected by the light cord that passes over a 5-kg pulley with I = 0.025 kg.m. If the system is released from rest, (with coefficient of friction between the block and ground of 0.3) calculate the angular acceleration of the pulley 100 mm

The two boxcars A and B have a weight of 17 000 lb and 36 000 lb, respectively. They are freely coasting down the incline when the brakes are applied to all the wheels of car A. The coefficient of kinetic friction between the wheels of A and the tracks is μ = 0.6. The wheels of car B are free to roll. Neglect their mass in the calculation. Suggestion: Solve the problem by representing single resultant normal forces acting on A and B, respectively. (Figure 1) Figure Part A μA Determine the magnitude of the force in the coupling C between the two cars. Express your answer to three significant figures and include the appropriate units.

Please show full work thank you

The collar of mass m is released from rest while in position A and subsequently travels with neg- ligible friction along the vertical-plane circular guide. Determine the normal force (magnitude and direction) exerted by the guide on the collar (a) just before the collar passes point B, (b) just after the collar passes point B (i.e., the collar is now on the curved portion of the guide), (c) as the collar passes point C, and (d) just before the collar passes point D. Use the values m = 0.4 kg, R = 1.2 m, and k = 200 N/m. The unstretched length of the spring is 0.8R.
