A weightless inextensible rope rest on a stationary wedge forming an angle `alpha` with the horizontal. One end of the rope is fixed on the wall at point A. A small load is attached to the rope at point B. The wedge starts moving to the right with a constant accelration a. The acceleration of the load is given by:

A

a

B

`2a sin alpha`

C

`2a "sin" alpha/2`

D

`gsin alpha`

Text Solution

Verified by Experts

The correct Answer is:
C
Net acceleration of load
`=2a cos ((pi-alpha)/2)=2a sin (alpha/2)`

A heavy cart is pulled by a constant force F along a horizontal track with the help of a rope that passes over a fixed pulley, as shown in the figure. Assume the tension in the rope and the frictional forces on the cart remain constant and consider motion of the cart until it reaches vertically below the pulley. As the cart moves to the right, its acceleration

A ball of mass 1kg is suspended by an inextensible string 1m long attached to a point O of a smooth horizontal bar resting on fixed smooth supports A and B. The ball is released from rest from the position when the string makes an angle 30^@ with the vertical. The mass of the bar is 4kg . The displacement of bar when ball reaches the other extreme position (in m) is

A weightless rigid rod with a load at the end is hinged at point A to the wall so that it can rotate in all directions (Fig). The rod is kept in the horizontal position by a vertical inextensible thread of length 1, fixed at its midpoint. The load receives a momentum in the direction perpendicular to the plane of the figure. Determine the period T of small oscillations of the system.

A wedge of mass M = 2m rests on a smooth horizontal plane. A small block of mass m rests over it at left end A as shown in figure. A sharp impulse is applied on the block, due to which it starts moving to the right with velocity v_(0) = 6 ms^(-1) . At highest point of its trajectory, the block collides with a particle of same mass m moving vertically downwards with velocity v = 2 ms^(-1) and gets stuck with it. If the combined body lands at the end point A of body of mass M, calculate length l . Neglect friction (g = 10 ms^(-2)) .

A car P is moving with a uniform speed 5sqrt3 m//s towards a carriage of mass 9 kg at rest kept on the rails at a point B as shown in figure. The height AC is 120 m. Cannon balls of 1 kg are fired from the car with an initial velocity 100m//s at an angle 30^@ with the horizontal. The first cannon hall hits the stationary carriage after a time t_0 and sticks to it. Determine t_0 . At t_0 , the second cannon ball is fired. Assume that the resistive force between the rails and the carriage is constant and ignore the vertical motion of the carriage throughout. If the second ball also hits and sticks to the carriage, what will be the horizontal velocity of the carriage just after the second impact?

A block of mass M is pulled along a horizontal frictionless surface by a rope of mass m as shown in A horizontal force F is applied to one end of the rope. Find (a) the acceleration of the rope and block (b) the force that the rope exerts on the block (c) the tension in the rope at its mid point

A uniform rope of mass (m) and length (L) placed on frictionless horizontal ground is being pulled by two forces F_(A) and F_(B) at its ends as shown in the figure. As a result, the rope accelerates toward the right. Tension (T) at the mid point of the rope is

A particle of mass m is attached to one end of a mass-less spring of force constant k, lying on a frictionless horizontal plane. The other end of the spring is fixed. The particle starts moving horizontally from its equilibrium position at time t=0 with an initial velocity u_0 . when the speed of the particle is 0.5u_0 , it collides elastically with a rigid wall. After this collision

A massless rod rigidly fixed at O. A sting carrying a mass m at one end is attached to point A on the rod so that OA = a . At another point B(OB = b) of the rod, a horizontal spring of force constant k is attached as shown. Find the period of small vertical oscillations of mass m around its euqilibrium position.
