Problem 2 A 0.5-kg block is pressed a distance d against a horizontal spring of constant 800 N/m. The block sits on a frictionless horizontal surface When the block is released from rest, it slides along the surface, its speed is 1.6 m/s when it leaves the spring (a) Calculate distance d. 4 cm Suppose that the sliding block (speed 1.6 m/s) crosses a rough section of the surface. The leugth of the section is 1m. The block has a...
A 12 kg block is pressed against a spring with spring constant k = 1424 N/m. The spring is normally 65 cm long but the block is pressed against it to compress the spring until it is only 27 cm long. The block is then released and the spring pushes it forward onto a frictionless surface. a)How fast is the block moving immediately after it leaves the spring? b) The mass then slides across a 2.5 m wide surface with...
A 1.6 kg block slides along a frictionless surface at 1.0 m/s . A second block, sliding at a faster 4.4 m/s , collides with the first from behind and sticks to it. The final velocity of the combined blocks is 2.5 m/s . Part A What was the mass of the second block? Express your answer to two significant figures and include the appropriate units.
Question 4 A 0.5 kg block slides on a frictionless surface onto a cart that has a rough surface. After sliding on the rough surface (uk = 0.30) of the cart over some distance, the block and the cart will come to the same speed of 0.4 m/s. The cart rolls frictionlessly. 0.5 kg 2 kg 0.4 m/s a. Is this a collision? If so, what kind of collision is it? b. What is the initial speed of the block...
A mass M slides upward along a rough plane surface inclined at angle \Theta\: Θ = 0.13 in radians to the horizontal. Initially the mass has a speed V_0\: V 0 = 2.11 m/s, before it slides a distance L = 1.0 m up the incline. After sliding this distance the new speed of the mass isV_0\: V 0 / 3 measured in m/s. What is the acceleration of the sliding mass? (Positive denotes acceleration up the incline; negative denotes...
