When a body of mass 0.25 kg is attached to a vertical massless spring, it is extended 5.0 cm from its unstretched length of 4.0 cm. The body and spring are placed on a horizontal frictionless surface and rotated about the held end of the spring at 2.0 rev/s. How far is the spring stretched?

An inclined plane of angle = 20.0 has a spring of force constant k = 500 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in Figure P6.61. A block of mass m = 2.50 kg is placed on the plane at a distance d = 0.300 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?
You decide to launch a rockof mass m1 using a tube containing a spring of spring constant k. When the spring is at equilibrium, it fills the entire tube. To launch a rock, you push it into the tube, compressing the spring a distance d, at which point a locking mechanism holds the spring(and the rock) in place. When the lockis released, the spring pushes the rock to the end of the tube where it will be launched into the air. The coefficient of kinetic friction between the rock and the inside surface of the tube is given by μk. You setup the launcher at an angle q above the horizontal with the spring end buried such that when the spring is compressed and locked, the rock is at ground level. a)Find the work done on the rock by non-conservative forces as it moves from the point of release to the end of the tube. Express your answer in terms of μk, m1, q, d, and any necessaryconstants. b) Find the velocity of the rockvfas it exits the launch tube in terms of μk, k, m1, q, d, and any…
Consider a Hot Wheels™ car with a mass of 121 g, that is pushed by a student along a track so that it is moving at 5 m/s. It hits a spring (k = 92.5 N/m) at the end of the track, causing it to compress. How far did the spring compress to bring the car to a stop? Calculate the answer in cm and make sure to include the unit. Report your final answer with three significant figures.
A man climbs a mountain. The man is of mass m falling freely in length h until the elastic rope starts to slow the fall at y = 0 and t=to= 0. At this time the climber has speed vo. The rope has length Lis fixed at point S and is without slack in the place where the climber fell. -The climber is in free fall until the rope starts to catch the fall. Set up the model that applies to free fall and derive the expression for the speed vo the climber has in the rope that starts to slow the fall. you can assume that the speed of the climber is just a function of y such that: dy dt =v(y) → L d²y ==v dt² S dv dy 2/2 2/2 y = 0 dy dt = v(y) ⇒ d²y dt² = V dv dy Figure 1: Climbing with mass m falling freely in length h until the elastic rope starts to slow down the fall at y = 0 and t = to = 0. At this time, the climber has speedvo. The rope has length L, is fixed at point S, and is without slack as the climber falls.
O Macmillan Learning A block of mass m = 2.15 kg slides along a horizontal table with speed vo= 1.00 m/s. At x = 0, it hits a spring with spring constant k = 73.00 N/m, and it also begins to experience a friction force. The coefficient of friction is given by μ = 0.100. How far has the spring compressed by the time the block first momentarily comes to rest? Ax = m wwwwwwwww Ax
QUESTION 25 A block with a mass of m slides at a constant velocity Vo on a horizohtal frictionless surface. The block collides with a spring and comes to rest when the spring is compressed to the maximum value. If the velocity of the block was doubled, what is the new maximum compression in the spring? The compression of the spring would be double (2x) the original compression A. В. The compression of the spring would be half (1/2x) the original compression. С. c The compression of the spring would be the same as the original compression. D. The compression of the spring would be a quarter (1/4x) the original compression. E. The compression of the spring would be quadruple (4x) the original compression
