Solve the following problem gene below:
Problem: A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 49.0 m/s2. The acceleration period lasts for time 10.0s until the fuel is exhausted. After that, the rocket is in free fall.
Part A: Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2.
I want you to clarify the physics in this above problem.
A 300 gram block is attached to a light horizontal spring. The block is free to slide on a horizontal table. Find how far beyond its equilibrium position will the spring stretch at its first maximum extension if the surface of the table is frictionl..
A hockey player got checked into the boards and was knocked unconscious. It takes 95N of force to drag the hockey player across the ice at a constant speed.
If the total momentum of a system is a constant, then we say that the total momentum is conserved. A consequence of Newton’s laws of physics is that the total momentum of a system is conserved whenever the net external force on the system is zero.
A proton has a speed of 0.80c.Calculate the rest energy of the proton. Calculate the total energy of the proton
