a 6-kg block slides along a frictionless horizontal surface. The block is acted on by two forces, a 4.5 N force to the left, and a 7.5N force to the right. At what rate is the 4.5N force doing work on
A 2.00 kg block is pushed against a spring with negligible mass and force constant k= 400 N/m, compressing it 0.22m. when the block is release, it moves along a frictionless, horizontal surface and th
An ice skater is spinning at 20rad/s about her longitudinal axis when she abducts her arms and doubles here radius of gyration about her longitudinal axis from 30 to 60cm. if her angular momentum is c
The Achilles tendon inserts on the calcaneus at a distance of 8cm from the axis of the ankle joint. If the force generated by the muscle attached to the Achilles tendon is 3000N and the moment arm of

Tips for Asking Questions
- Provide any and all relevant background materials. Attach any necessary files to ensure your Tutor has all the required information to answer your question as completely as possible.
- Set a compelling price. While our Tutors are eager to answer your questions, offering a compelling price speeds up the process by avoiding any unnecessary price negotiations.
1. Can you show me step by step how to solve this problem?:
- The Earth’s rate of rotation is constantly decreasing, causing the day to increase in duration. In the year 2000 the Earth takes about 0.548 s longer to complete 365 revolutions than it did in the year 1900.
- (a) What is the average angular acceleration of the Earth?
- (b) If this average acceleration remains constant, in what year will the Earths rotation come to rest?
2. I do not understand this Ideal Gas Law and Kinetic Theory question. Can you help me set it up?
- A spherical balloon is made from a material whose mass is 3.00-kg. The thickness of the material is negligible compared to the 1.5-m radius of the balloon. The balloon is filled with helium (He) at a temperature of 305-degrees K and just floats in the air, neither rising nor falling. The density of the surrounding air is 1.19-kg/m^3. Find the absolute pressure of the helium gas
