You have landed on an alien planet and because you have nothing better to do with your time, yoù have decided to do a physics experiment with a block. Your experiment is shown above. A 1701 kg block is pressed against a wall (= 0.9) by a horizontal spring with a spring constant of 45,500 N/m. The normal force on the block is 12,285 N and the block is stationary. Assuming the static friction force is maximized, determine how much the spring has been compressed & g (the free fall acceleration on this planet). {= 0.27 m ✓ 9 =

How do you measure the mass of an astronaut in orbit? (You can't just use a scale!) For the 1973 - 1979 Skylab program (Skylab was a space station that predated the current International Space Station), NASA engineers designed a Body Mass Measuring Device (BMMD). This is essentially a chair of mass m mounted on a spring with a carefully measured spring constant ks = 605.6 N/m. (The other end of the spring is connected to the Skylab itself, which has a mass much larger than the astronaut or the chair, and so remains essentially fixed as the astronaut oscillates.) The period of oscillation of the empty chair is measured to be 0.90149 s. When an astronaut is sitting in the chair, the period is 2.12151 s. What is the astronaut's mass? Please describe your reasoning!

I need help solving the equations symbolically and I don't know how to get the m value for the first part.

A box is motionless, sitting on a ramp with an incline of 0 =54.4 ° being pulled in the direction up the ramp by a spring with a spring constant of k=150 N/m that is stretched x=6.4 m. The coefficient of friction between the ramp and the box are u s=0.53 and u k=0.15 and the friction force is going down the ramp. What is the mass of the box? Solve symbolically: Solve numerically: m= Units: If the box starts moving up a ramp with an acceleration of a=2.41 m/s, what is the new length that the spring will stretch? Solve symbolically: Solve numerically: Units:

Please answer this University Physics Question.

The tension in a ligament in the human knee is approximately proportional to the extension of the ligament, if the extension is not too large. If a particular ligament has an effective spring constant of 160 N/mm as it is stretched, what is the tension in this ligament when it is stretched by 0.760 cm? What is the maximum compression of the spring? The spring sends the block back to the left. How high does the block rise?

A spring with a spring constant of 51.1 N/m is hung from the ceiling. A block is then attached to the free end of the spring. When released from rest, the block drops 0.160 m before momentarily coming to rest, after which it moves back upward. What is the mass of the block?

A block of mass m = 0.71 kg attached to a spring with force constant 106 N/m is free to move on a frictionless, horizontal surface as in the figure below. The block is released from rest after the spring is stretched a distance A = 0.13 m. (Indicate the direction with the sign of your answer. Assume that the positive direction is to the right.) (a) At that instant, find the force on the block. N (b) At that instant, find its acceleration. m/s? Need Help? Read It
