In Figure, a 3.5 kg block is accelerated from rest by a compressed spring of spring constant
Question:
In Figure, a 3.5 kg block is accelerated from rest by a compressed spring of spring constant 640 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction ?k= 0.25. The frictional force stops the block in distance D = 7.8 m. What are??
(a) The increase in the thermal energy of the block-floor system,
(b) The maximum kinetic energy of the block, and?
(c) The original compression distance of the spring?
- No friction D. (H4)
Step by Step Answer:
a The vertical forces acting on the block are the normal force upward and the force of gr...View the full answer

Skateboarding is a fun and popular activity among young people, in which the participant stands on a small board with wheels and navigates different surfaces. It is considered an extreme sport and there are professional competitions for different disciplines like vertical and street skating. To start skateboarding, focus on maintaining balance and having fun. To control the board, use your feet and keep your body\'s center of mass over the skateboard. The most stable and safest riding position is to have your front foot just behind or on the front bolts of the board and your back foot close to the back of the board, near or on the heel. This position also makes quick kick turns easier. Once you have mastered the basics, you can learn various tricks to impress others. In terms of mechanics, skateboarding involves the principles of force and torque. The rider exerts force on the skateboard to make it move, and torque is used to turn the board or perform tricks. Friction between the wheels and the ground also plays an important role in allowing the rider to control the speed and direction of the board. Energy is also involved in skateboarding, specifically the transfer of potential energy to kinetic energy. When a rider jumps on a skateboard, they transfer potential energy stored in their muscles into kinetic energy, which propels the board forward. The rider can also transfer kinetic energy into potential energy by performing an aerial trick and then landing back on the board.
