Two blocks of masses $m_1=5 \;kg$ and $m_2= 6\;kg$ are connected by a light string passing over a light friction less pulley as shown in fig.
A 70 N block and a 35 N block are connected by a massless inextendable string which is wrapped over a frictionless pulley as shown in Figure 1. If the pulley is massless and the surface is frictionless, find the magnitude of the acceleration of the 35 N block. A) 3.3 m/s2 B) 2.3 m/s2 C) 1.3 m/s2 D) 9.8 m/s2 E) 4.9 m/s2 Ans: Two blocks are connected by a light string that passes over a frictionless pulley as shown in figure below. The system is released from rest when the spring is unstretched. If the hanging block (15 Kg) falls a distance 0.2 m before coming to rest. Find the coefficient of kinetic friction between the block of mass 5 Kg and the surface.
Determine (a) the acceleration of each object and (b) the tension in the two strings. Figure P4.62. 63. A 2.00-kg aluminum block and a 6.00-kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle θ = 30.0°) as shown in Figure P4.63.
