- I'm not sure how to work this problem. The solutions give the answer to be V1f=0.20 m/s, v2f=2.75 m/s for part A. For part B the solutions give the answer to be x=0.22 for maximum compression for the spring. I attached a picture of the problem.A simple pendulum is made from a 0.666-m-long string and a small ball attached to its free end. After the ball is released pulled to one side through a small angle and then released from rest. After the ball is released, how much time elapses before it attains its greatest speed?Hanging Mass: A block of mass 14.1 kg is connected to a light cord of length 351.3 cm and a spring with an equilibrium length of 33.4 cm. The block hangs motionless as shown in the figure. The spring has a spring constant of 1799 N/ m. As the block hangs in equilibrium, the spring is horizontal and the cord makes an angle of 24 ° with respect to vertical. T k M (a) What is the tension in the cord? (b) How far is the spring stretched from its equilibrium length?
- A mass resting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. It takes 3.0 JJ of work to compress the spring by 0.13 mm . If the spring is compressed, and the mass is released from rest, it experiences a maximum acceleration of 12 m/s2m/s2. Find the value of the mass. Express your answer to two significant figures and include the appropriate units.Q810.
- N 2. A horizontal spring is compressed by 25.0 cm. A 640.0 g box is then placed against the spring and then released. After travelling 3.15 m from the release point, the speed of the mass is 5.68 m/s. The coefficient of friction is 0.34. What is the spring constant of the spring? mi Tum Tm =A block is hung from the end of a spring with spring constant 15 N/m and made to vibrate up and down with a maximum speed of 0.4m/s. The spring is held up by a force sensor, which is set to read 0N when the block is at rest on the end of the spring. The graph attached belwo shows the reading on the force sensor over time as the block vibrates. Plot the position-time and velocity-time graphs for the blocks as it vibrates. Explain with work and in words how you determined the shapes of these as well as their amplitudes.A 205 g object is attached to a spring that has a force constant of 76.5 N/m.

Umax = m/s Find the locations of the object when its velocity is one-third of the maximum speed. Treat the equilibrium position as zero, positions to the right as positive, and positions to the left as negative. position: cm position: cm
- 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?Questions a,b and cA 205 g object is attached to a spring that has a force constant of 74.5 N/m.
