The co–efficient of friction between them is μ , the maximum a .s acceleration with which the block M may move so that m also moves along with w it is w m a) g μ b ) g/ μ M w a c) μ /g d) μ 2g www.sakshieducation.com www.sakshieducation.com 9. A >block</b> <b>of</b>. A string is attached to the block, and is pulled with a force of 60.0 N at an angle θ above the horizontal. After the block is pulled through a distance of 2.00 m, its speed is 2.70 m/s, and 43.0 J of. Physics. A block of mass 3m is placed on a frictionless horizontal surface, and a second block of mass m is placed on top of the first block. A block of mass m is placed over rough plank of mass 2m and length / = 1 m and complete system is placed over smooth horizontal surface as shown in figure. If block is given velocity vo = 2 m/s, then choose the correct options. m (m = 1 kg) u = 0.1 Smooth 2m Velocity of block at the time of leaving plank is 1 m/s Velocity of plank at the time. . In the figure shown, a block A of mass m is rigidly attached to a light spring of stiffness k and suspended from a fixed support. Another block B of same mass is just placed on it and the blocks are in equilibrium. Suddenly, the block B is removed. Choose the correct options afterward.A. Block A will start SHM.B.Amplitude of oscillation of the block A is mg / k.D. Period of oscillation is 2.

I get (b) SHM is described by the expression y=Asinomegat where A is maximum amplitude and omega=(2pi)/T is the angular frequency. We also have Velocity v=doty=omegaAcosomegat Acceleration a= dotv=-omega^2Asinomegat=-omega^2y The block will not leave the plank so long as its gravitational force is less than centrifugal force experienced by it due to circular motion.
