- The final set of this lab has you hanging an unknown mass on a spring (for which you have determined the spring constant, k). If you find the spring constant k = 24.0 N/m, what is the mass of an unknown object if it displaces the spring 4.40 cm? Give your answer in GRAMS to 3 significant figuresAn ideal spring can compress 2.33 cm by a force of 555 N, a block of mass m = 3.18 kg is released from rest on an inclined plane, the onclination of the plane is 32 degrees, the block rest momentarly when the spring is compress 5.48 cm. Find the distance d that the block travels from the begining of the motion until it reaches the spring. (g = 10 m/s2 ).Derive an expression for the maximum displacement possible for the block that will allow the block to still remain at rest. Express your answer in terms of MM, kk, μk, μs, and physical constants, as appropriate.
- a) Given the following ideal Atwood machine in an elevator accelerating down at ae = 4.9 m/s2, with m1 = 10 gram (two nickels) and m2 = 5 gram (one nickel) as shown, what is the tension T in the string in millinewton (mN)? (Hint: the upward arrow on ae is correct and just means use "positive is up" conventions for the elevator itself, so here we have ae = -4.9 m/s2 to be put into Einstein's rule that we discussed.) b) Exact same Atwood machine as the previous problem (two nickels and a nickel in an elevator accelerating down at 4.9 m/s2), but now how much time (s) does it take m1, starting from rest, to fall 25 cm relative to the inside of the elevator? I labeled it a and b because they are connected to each other. Please help, thanks!(Figure 1) shows a F = 6.4 N force pushing two gliders along an air track.

Unfortunately, the skis run out of fuel after only 10 s. A. What is Sam’s top speed? B. How far has Sam traveled when he finally coasts to a stop?4With friction, what is the magnitude of the acceleration of the block after it begins to slide down the plane?

At the top of an inclined plane in the rocketship, you place a block of mass m. The length of the incline is L. If you let go of the block, what is the time taken by the block to reach the bottom of the incline? θ is the angle that the incline makes with the horizontal, and you make sure that the incline cannot move. Assume no friction.Sketch the correct direction of the acceleration vector a⃗ a→ for the system shown in (Figure 1). Sketch the correct direction of the velocity vector v⃗ v→.
