A block attached to a horizontal spring is pulled to the right a distance of 21.0 cm from the equilibrium position. The block is released and the block-spring system undergoes SHM at f- 1.29 Hz. Assuming that positive is to the right, determine at 0.500 s after release the block's displacement, velocity, and acceleration. Neglect friction. (Indicate the direction with the sign of your answer) (a) displacement cm (b) velocity cm/s (c) acceleration cm/s2

Block 1 (20 kg) is pulled by a rope from left to right up a ramp which is inclined 45 degrees from the horizontal. The rope pulls on block 1 with a force of 360 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.2. Assume that the x-axis is parallel to the incline and positive in the direction up the incline. What is the magnitude of the...

Determine the magnitude of the speed of block B and the speed and acceleration of Block A 9 seconds after being released from rest. Block B accelerates at 3 m/s2. Give you answer rounded to three significant figures (don't include negative signs). ΑΣ Speed of block B = Number Units Acceleration of block A = Number Units Speed of block A= Number Units

1. In 0.720 s, a 6.95-kg block is pulled through a distance of 3.70 m on a frictionless horizontal surface, starting from rest. The block has a constant acceleration and is pulled by means of a horizontal spring that is attached to the block. The spring constant of the spring is 460 N/m. By how much does the spring stretch in kg? 2. An object attached to a horizontal spring is oscillating back and forth along a frictionless surface. The...

) A 2 kg block is attached to a rope. The rope is wound around a pulley which has a radius of 0.2 m. You do not know the mass of the pulley, or the geometry of the pulley. The block is released from rest, and you notice it has a speed of 3 m/s after falling 1.5 m. a) What is the angular velocity of the pulley when the speed is 3 m/s? b) Use the fact that energy...

A ball swings in a vertical circle at the end of a rope 1.50 m long. When the ball is 36.9° past the lowest point on its way up, its total acceleration is (-22.5120.2j) m/s2 For that instant, do the following. (a) Sketch a vector diagram showing the components of its acceleration. (Do this on paper. Your instructor may ask you to turn in the sketch.) (b) Determine the magnitude of its radial acceleration m/s2 (c) Determine the speed of...
