DYNAMICS-15 A block with a spring attached to one end slides along a rough surface with an initial velocity of 7 m/s. After it slides 4 m, it impacts a wall for 0.1 s, and then slides 10 m in the opposite direction before coming to a stop. If the block's deceleration is assumed constant and the contraction of the spring is negligible, what is the average acceleration of the block during impact with the wall? spring block +X (A)...
A 10-lb collar is attached to a spring and slides without friction along a fixed road in a vertical plane. The spring has an undeformed length of 1.5 ft. and a constant k = 2 lb/ft. Knowing that the collar is released from rest in the position shown, determine the velocity of the collar at point B 1.5 ft 10 lb 1.5 ft 1.5 ft + 1.5ft --
A block of ice slides along a frictionless horizontal track with a speed of 1.2 m/s. At the end of the track is a horizontally mounted spring. The ice block slides along the track until it makes contact with the spring causing it to compress. What is the speed of the ice block when the spring has been compressed by 60% of the maximum compression length?
A 3 lb*f collar is attached to a spring and slides without friction along a circular rod which lies in a horizontal plane. The spring has a constant k = 1.5 lbf/in and is undeformed when the collar is at B. If the speed of the collar is 6 ft/s when it passes through point D, determine the speed of the collar (in ft/s) as it passes point B. Please include four significant figures in the final answer. Thank you...
13.2) A 1.3 -kg block slides along a horizontal surface with a coefficient of friction μk = 0.274. The block has a speed v = 2.28 m/s when it strikes a massless spring head-on. a. If the spring has a force constant k = 30.9 N/m, how far is the spring compressed? b. What minimum value of the coefficient of static friction, μs, will assure the spring remains compressed at the maximum compressed position? c. If μs is less than...
A 2.5-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. The spring has an undeformed length of 4 in and a constant k = 20 lb/ft. Knowing that the collar is at rest at C and is given a slight push to get it moving, determine (a) the velocity of the collar as it passes through point A, and (b) the force exerted by the rod on the collar as...
A 1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. The spring has an undeformed length of 5 in. and a constant k-25 lb/ft. Knowing that the collar is released from being held at A determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through B. (Round the final answer to two decimal places.) 3 in 7 in The...
A 3 lbf collar is attached to a spring and slides without friction along a circular rod which lies in a horizontal plane. The spring has a constant k = 1.5 lbf/in and is undeformed when the collar is at B. If the speed of the collar is 6 ft/s when it passes through point D, determine the speed of the collar (in ft/s) as it passes point C. с 3 lb B. D 12 in. 5 in.
A horizontal spring is lying on a frictionless surface. One end of the spring is attached to a wall whle the other end is connected to a movable object. The spring and object are compressed by 0.082 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 11.9 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.041 m relative to its unstrained length? _______ m/s
A box with a mass of 1.80 kg slides along a flat track with friction until it makes contact with a horiztonally mounted spring. At the instant that the box makes contact with the spring the box has a velocity magnitude of 2.00 m/s. The box slides and slows down until it comes to a rest after compressing the spring 11.0 centimeters. If the coeficient of kinetic friction between the track and box is 0.56, what is the spring constant...
