Hi i was wondering if i can have some help with these questions please:)
A spaceship in deep space, initially at rest, is struck by an asteroid. As a model for the ship, consider it to be a thin, rectangular rod, and assume the collision takes place on the top surface. Fo
Very easy!! please help asap!!! I will tip very well depending on how soon you answer!!

A rock is dropped from rest into a canyon and strikes the canyon floor after 1.9 s. Approximately how deep is the canyon?
Hi, I a looking for some help to understand these questions. Can someone help?
A puck is sliding on flat ground with an initial speed to 7 m/s and comes to rest after 1.25 s. Approximately which is the coefficient of kinetic friction between the puck and the ground?
A car starts from rest and accelerates at a rate of 9 m/s 2 for 4 seconds and then accelerates (brakes) at a rate of -3 m/s 2 for 2 seconds. How far did the car travel in 6 s? I need a quick answer on

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
