6. A 5-kg block is pressed against a spring near the bottom of a 30° inclined plane. The spring, (spring constant 450 N/m) is compressed by 0.50 m.When released, the spring projects the block toward the top of the incline. The coefficient of kinetic friction between the block and the inclined plane is 0.3. (a) What is the speed of the block at the instant the block first returns to its equilibrium length? ans [3.9 m/s] (b) Calculate the speed...

The spring bumper is used to
arrest the motion of the 8 lb block, which is sliding toward it at
5 ft/s . As shown, the spring is confined by the plate P and wall
using cables so that its length is 1.5 ft.
(Figure 1)
Part A
If the stiffness of the spring is k = 50 lb/ft, determine the
required unstretched length of the spring so that the plate is not
displaced more than 0.2 ft after the...

1. (30 points) A 2-kg block A is pushed up against a spring compressing it a distance r-0.1 m (i.e., the spring is unattached to the block). The block is then released from rest and slides down the 20° incline u it strikes a 1-kg sphere B that is suspended from a 1-m inextensible rope. The spring constant 800 N/m, the coefficient of friction between A and the ground i length of the spring d-1.5, and the coefficient of restitution...

Problem 3: The 50-1b block rests on the rough surface for which the coefficient of kinetic friction is 0.2. A force F = (40 + s2) lb, where s is in ft, acts on the block in the direction shown. If the spring is originally unstretched (s = 0) and the block is at rest, determine the power developed by the force the instant the block has moved s = 1.5 ft. F 30° k = 20 lb/ft

The spring bumper is used to arrest the motion of the 9 lb
block, which is sliding toward it at 5 ft/s . As shown, the spring
is confined by the plate P and wall using cables so that its length
is 1.5 ft.
If the stiffness of the spring is k = 50 lb/ft, determine the
required unstretched length of the spring so that the plate is not
displaced more than 0.2 ft after the block collides into it....
A block of mass 3.00 kg is pressed against a spring (k=3,100N/m) near the bottom of a board inclined at θ = 28.0°
A block of mass 3.00 kg is pressed against a spring (k=3,100N/m)
near the bottom of a board inclined at θ = 28.0°, as shown in
Figure A2.08. When released, the block is projected up the incline
and the spring expands by 14.0 cm to its normal length. Using the law of conservation of energy, determine
the maximum distance (d) traveled by the block up the incline,(a) in the absence of friction.(b)when the coefficient of kinetic friction between the block
and...

6. For this series of 4 questions, a 1-1b ball is dropped from rest and falls a distance before striking the smooth plane at A. It bounces from the plane, and then strikes the plane again. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 2) If the ball is dropped form rest at a height h = 4.5 ft, and the coefficient of restitution...

The spring has a stiffness of k = 50 lb/ft and an unstretched length of 2.00 feet. As shown, it is confined by the plate and wall using cables so that its length is 1.5 feet. An 8 pound block is given a speed VA, when it is at A, and it slides down the incline having a coefficient of friction of 0.40. If it strikes the plate and pushes it forward 0.40 feet before stopping, determine its speed at...
