A block of mass sqrt(3) kg rests on a horizontal frictionless surface. What will be the acceleration of the block if it is subjected to two forces as shown in the figure.

Two blocks of masses m and m' are connected by a light spring on a horizontal frictionless table . The spring is compressed and then released . Find the ratio of acceleration of masses .

Block A of mass 35 kg is resting on a frictionless floor.

A block of mass M = 2 kg with a semicircular track of radius R = 1.1 m rests on a horizontal frictionless surface. A uniform cylinder of radius r = 10 cm and mass = 1.0 kg is released from rest from the top point A. the cylinder slips on the semicircular frictionless track. The speed of the block when the cylinder reaches the bottom of the track at B is (g =10ms^(-2))

A body of mass m=3.90 kg slides on a horizontal frictionless table with a speed of v=120 ms^(-1) . It is brought to rest in compressing a spring in its path. How much does spring is compressed, if its force constant k is 135 Nm^(-1) ?

Two blocks of masses m and M are placed on a horizontal frictionless table connected by light spring as shown in figure. The Mass M is pulled to the right with a force F It the acceleration of mass m is a then the acceleration of M will be .
