A block of mass 100.0 g rests on a frictionless, horizontal plane. It is pressed firmly against a horizontal spring with spring constant 2000.0 N/m (assume that the spring is massless). The object is held in position such that the spring is compressed 1.00 cm shorter than its undisturbed length. If the block is suddenly released, at what speed will it be traveling when it is free of the spring?
Q2)) A block of mass m= 4 kg slides down a frictionless plane inclined 30° to the horizontal .

A block with mass M rests on a frictionless surface and is connected to a horizontal spring of force constant k. The other end of the spring is attached to a wall (Fig. P14.68). A second block with mass m rests on top of the first block. The coefficient of static friction between the blocks is ms. Find the maximum amplitude of oscillation such that the top block will not slip on the bottom block. Suppose the two blocks are...

1. The figure shows a box with mass m1 on a frictionless plane inclined at angle ?1. The box is connected via a cord of negligible mass to another box with mass m2 on a frictionless plane inclined at angle ?2 (> ?1). The pulley is frictionless and has negligible mass and assumes that the setup is on the surface of the earth. a) Provide free-body force diagram for both boxes. b) What is the acceleration in terms of m1,...
A block of mass m1 = 3.7 Kg on a frictionless plane inclined at an angle θ = 30° is connected by a cord over a massless frictionless pulley to a second block of mass m2 = 2.3 Kg. a) What is the magnitude of the acceleration of each block? b) What is the Tension of the cord? c) What is the Normal force?
A block with mass m is on a frictionless surface tilted at an angle of 40 degree above horizontal. What is its acceleration?
On a frictionless surface. a block of mass M moving at speed v collides elastically with another block of the same mass that is initially at rest. After the collision, the first block moves at an angle θ to its initial direction and has a speed U/2. The second block's speed after the collision is 3 4 (B) 2 2 U) (E) ut cose
