3. A box of mass m=15 kg at the packaging section of a factory comes to the top of a (0=37°) with speed vo and slides down where it is picked up for shipment. In order to avoid damage to the box a spring is used with force constant k=100N/m and the ramp maximum force Fmax=100N. The box slides a distance of -4 m down the incline before it hits the spring is 0.75. ramp as shown. The coefficient of kinetic friction between the box and entire a) Find the work done by the normal force and Vo gravity friction force on the box until it hits the spring. b) Find the maximum speed of the box at the top of the ramp if the box is to be picked up in the spring is www when maximum compression.
A block of mass m= 2.0 kg is released from rest on an inclined plane at a height of h = 1.5 m. It moves down the rough incline with slope theta= 30.0°and continues on the horizontal frictionless surface. As shown in the figure, there is a spring with negligible mass and force constant k = 300 N/m. The coefficient of kinetic friction between the block and the incline is 0.250 What is the speed of the block when it gets down on the horizontal surface before it touches the spring? The box continues to move on the horizontal surface and compresses the spring. What will be the maximum compression of the spring?
The torsional spring has a stiffness of 20 N-m/rad and is undeflected when the 3-kg uniform slender bar is in an upright position.
