A 500-g block is released from rest and slides down a frictionless track that begins 2.50 m above the horizontal, as shown in the figure below. At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with a spring constant of 10.0 N/m. Find the maximum distance the spring is compressed. m
A block of mass 2.1 kg is sitting on a frictionless ramp with a spring at the bottom that has a spring constant of 525 N/m (refer to the figure). The angle of the ramp with respect to the horizontal is 12 degrees. a. The block, starting from rest, slides down the ramp a distance 68 cm before hitting the spring. How far, in centimeters, is the spring compressed as the block comes back to momentary rest? b. After the block comes to rest, the spring pushes the block back up the ramp. How fast, in meters per second, is the block moving right after it comes off the spring? c. What is the change of the gravitational potential eneregy, in joules, between the original position of the block at the top of the ramp and the position of the block when the spring is fully compressed?
5. A 60 kg circus performer is swinging from a trapeze bar.A: She is 10 m off the ground with a speed v1. The spring-board platform below her is atits equilibrium length.B: She lets go of the trapeze bar and lands on th spring-board platform, which compresseswhen she lands on it. When she is stationary, she is 2 m off the ground and the springis maximally compressed.C: The spring-board extends and launches her back into the air. As soon as the spring istotally relaxed again, the performer is 3 m off the ground and has a speed v2.D: The performer lands on a platform 10 m above the floor, and she stands stationary. a. Her initial speed v1 = 10 m/s. What is her total energy at point A? b. Between points A and B, assume none of her energy is lost to heat or friction. Whenshe is stationary on the compressed platform at B, how much energy is stored in thespring-board platform? c. When the spring-board platform is fully released at point C, what must her speed v2 be?
1. Sam, whose mass is 75 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 200 N and a coefficient of kinetic friction on snow of 0.10. 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?
As shown in the figure below, a box of mass m = 5.80 kg is sliding across a horizontal frictionless surface with an initial speed vi = 3.10 m/s when it encounters a spring of constant k = 2350 N/m. The box comes momentarily to rest after compressing the spring some amount xc. Determine the final compression xc (in m) of the spring. m
1. A block of mass m is pushed against (but not attached to) a spring with stiffness k so that the spring is compressed a distance Ar. When released, the block slides across the frictionless surface of a shelf a height h above the floor, the then falls to the floor. a. What is the speed of the block at the moment it leaves the shelf? V2 = b. What is the speed of the block at the moment just before it hits the ground? Vr =
1. Consider the setup shown below: a block with mass m; sits on a table with friction coefficient u between the table and itself, attached on one side to a spring with stiffness k, and on the other side to a cord with negligible mass that wraps over a frictionless pully and supports a second block with mass m2 that's suspended in the air over the edge of the table. The friction between block 1 and the table is not enough to hold up block 2 so that, when it's released from rest, the spring stretches a distance Ax before the system comes to rest. a. Draw and label a free-body diagram for each block. (Use the gridlines to make sure that the relative lengths of your vector arrows are correct.) k m1 block 1: block 2: m2 b. What is the kinetic friction coefficient between block 1 and the table?
Your doctor has told you to watch your weight. Of course, your weight comprises two factors, so you assume that she wants you to watch both your mass and the local value of g. Which explains why you are carrying a small mass mm on an elastic band wherever you go. Most of the time, the elastic band is stretched by a distance of 2.1 cm. However, when you have finished lunch, you go into a very tall building and take the high speed lift (or elevator depending on where you live). Soon after the doors close, you notice that the band (which has linear elastic properties) is stretched by a total distance of 3.5 cm. a) At what rate is the lift accelerating? _____ m.s−2 b) Your doctor will want to know the factor by which your weight has increased after that lunch. Suppose that you stand on scales in the lift while it is accelerating as described above. According to the scales, your weight has increased by a factor of _____ My answers are a)6.6 and b)1.67 but they're wrong.

1. A child's toy uses a spring to launch a 135 g-ball vertically upwards with a time-varying force which starts at t=0 s and lasts 0.25 s. The force is given by F(t)=10N(1-t/0.25s) and is directed straight up. Air drag can be ignored in this problem. A. What is the velocity of the ball after the 0.25 s passes and the ball leaves the launcher? Hint: you need to take gravity into consideration for this problem. B. After the ball leaves the launcher, how high does it get in the air?
