The position of an object as a function of time is given 62 by x At - Bt C, where A- 8.0 m/s2, B 6.0 m/s, and C 4.0 m. Find the instantaneous velocity and acceleration as functions of time.

Calculate the minimum amount of work needed to move a 400 kg rocket from Earth's surface to the International Space Station in orbit 300,000 m above Earths surface. Solve for the minimum amount of work needed to move the payload to the ISS. Start with general equations and explain what you are doing and why you did what you did. Evaluate your solution. Describe how you evaluated your answer and whether or not you think your answer is reasonable.

Stuck need help! The class I'm taking is physics for scientists and engineers! Problem is attached. please view attachment before answering.  Really struggling with this concept. Any help will be greatly appreciated! Please detail explain so I can fully understand how to solve.  Thank you so much.

Help.!!!

A football coach walks 12 meters westward, then 16 meters eastward, then 22 meters westward, and finally 6 meters eastward. For this motion, what is the distance moved?

Object 1 is located at position (2,3)m. Object 2 is located at position (8,11)m. a) What is the displacement vector (Ar12) that points from the position of Object 1 to the position of Object 2? b) What is the magnitude of the displacement vector ( |712|)? (A: 10 m)

I need help with number 3

Choose one equation (and only one) from the equation sheet that would let you solve the problem posed. Then define which variables in the equation go with what numbers from the problem itself (not from other problems), and define which variable is being solved for. Do not actually solve the problem numerically or algebraically, just pick the one equation and define the relevant knowns and single unknown. Don’t forget to include direction when called for by a vector variable. 1) A single mole of Carbon Dioxide has a mass of 44 g, and at 1.00 atm of pressure and 20oC (293K) it occupies 22.4 liters. At what speed will you find the peak of its speed distribution function?
