C &page=11# You are logged in as Gavin Ritche The sun has a mass of 1.99x10^30 kg and a radius of 6.955x10^8 m. What would be the weight of a 76.5 kg astronaut if she could stand on the surface of the sun? Answer: Next page DELL

02 Point material of mass 1 Kgr moves along the x-axis under the influence force F, which opposes the motion and is proportional to its square of speed with proportionality constant B=2. There is no gravity. A) Find the velocity and position of the material point for t > 0, if for t = 0 u = 2 m/s and x=0. B) Investigate your results: 1) if they satisfy the initial conditions, 2) if they have the right dimensions and 3) if in the limit t →∞ they logically give and expected results.

4 An Atwood's machine that has a frictionless massless pulley and mass- less strings has a 2.00[kg] object hanging from one side and 0.000004 [kiloton (kt)] object hanging from the other side. a) Draw the Free Body Diagram for this situation. b) What is the speed of each object 1.50 s after they are released from rest? c) At that time, what is the velocity of the center of mass of the two objects? d) At that time, what is the acceleration of the center of mass of the two objects?

Part A Suppose an apple (mass 200 g) sits at the edge of a cliff with height h. The apple then tips over the edge and hits the ground with a speed of 27 m/s. How tall is the cliff?

#2 Can someone help me with the question, I’m confused.

In a loop-de-loop ride at the fair a 200 Newton child experience as a 100 Newton apparent weight at the top of the loop. The diameter of the ride is 12 m. a. How fast is the child traveling at the top of the ride? b. Neglecting friction how fast is the child traveling at the bottom of the ride. c. what is the child's parent wait at the bottom of the ride d. In the reference frame of the child are they accelerating? What role does a child's inertia force play?

QUESTION 5 Problem A new type of force was discovered by physicists with the following expression: a Fnew + Bex + 3x4 where alpha & beta are constants, and x is the position. The expression above was obtained from the interaction of a massless Higgs Boson (a type of particle) and a black hole. Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do to achieve this feat? (For simplicity, consider that no energy is lost in the process) Solution determine the work done we apply the following W = dx Evaluating the above, we get W = e + for the limits from x¡ to xf substituting x1 and x2 as the limits, the work done is expressed as W = | + B X1 ( x15 . x25 )

Review I Constants I Periodic Table A ledge on a building is 16 m above the ground. A taut rope attached to a 4.0-kg can of paint sitting on the ledge passes up over a pulley and straight down to a 3.0-kg can of nails on the ground. Part A If the can of paint is accidentally knocked off the ledge, what time interval does a carpenter have to catch the can of paint before it smashes on the ground?

A Moving to another question will save this response. Quèstion 11 Newton's second law of motion states that O a. Acceleration of an object is directly proportional to the force and inversely proportional to its volume. O b. Acceleration of an object is directly proportional to the force and inversely proportional to its mass and direction of acceleration will be the opposite to the direction of force. O C. Acceleration of an object is directly proportional to the force and inversely proportional to its mass an direction of acceleration will be the same as direction of force. d. Acceleration of an object is inversely proportional to the force and directly proportional to its mass and direction of acceleration will be the same as direction of force.

I understand for static equilibrium all the forces should sum up to zero but I'm just not understanding how I should have found these answers.

Can i get help with this question
