The amount a string stretches varies linearly with the mass applied to the spring, (then a video) With no additional mass, the hanger was 30.6 cm off the ground. With 150 grams of additional mass, the hanger was 16.2 cm off the ground.
A wooden block stretched the spring so the hanger was 21.3 c

The amount a string stretches varies linearly with the mass applied to the spring, as can be seen in the video. In the video, with no additional mass, the hanger was 30.6 cm off the ground. With 150 grams of additional mass, the hanger was 16.2 cm off the ground. A wooden block stretched the spring so the hanger was 24.7 cm off the ground. Determine the mass of the wooden block, to at least 1 decimal place. grams

8. A spring stretches 3 cm when a 5 g object is hung from it. The object is replaced with a block of mass 50 g which oscillates in simple harmonic motion. What is the period of the motion? 9. It is known that a load with a mass of 25 g will stretch a spring 5 cm. The spring is stretched an additional 30 cm, and then released. (a) What is the spring's constant? (b) What is the period...

(1 point) A physics student wants to measure the stiffness of a spring (force required per cm stretched). He knows that according to Hooke's law, there is a linear relationship between the distance a spring is stretched and the force needed to stretch the spring. He collects some data by measuring the force applied to the spring when he stretches the spring by some amount. The plot and the least squares fit is given below Force versus Distance Stretched 0...

Initially, a 0.280kg mass is hung vertically from a spring. The spring stretches by 2.78 cm. Then, it is stretched an extra 4.15 cm, let go, and allowed to oscillate. Determine a) the spring constant b) the angular frequency c) the frequency d) period (Please show steps clearly so I can understand how you got the answers you did. THANK YOU!)

asking for question 2 and part c of 1
Fish are hung on a spring scale to determine their mass (most fishermen feel no obligation to report the mass truthfully). (a) What is the force constant of the spring in such a scale if it stretches 6.49 cm for a 11.3 kg load? 1706.317 N/m (b) What is the mass of a fish that stretches the spring 5.50 cm? 9.58 kg (c) How far apart are the half-kilogram marks on...

Need help with this urgently please!
1. Spring and mass system a) (10 pts) You have a spring of length 50 em and a block of mass 150 grams. When you hang the block from the spring you measured the length of the spring to be 52.5 cm. Then you pull the block down by 4.5 cm and release to set it in oscillation and measure the time period, T, using a stopwatch. What value of T would you expect...

Find the amplitude, angular frequency, phase constant, frequency, and period of the motion. (b) Where is the boat at t 1 s? (c) Find the velocity and acceleration as functions of time t. (d) Find the initial values of the position, velocity, and...

A Block of Mass 0.5 Kg is placed on top of a light, vertical spring of spring constant 50 N/m, causing the spring to compress some amount. The block is then pushed downwards by a persons hand so that the spring is compressed an additional 15 cm. The block is then released from rest, so that it travels upward and then leave the spring. A. What is the kinetic energy of the block as it leave the spring? B. What...

3. A spring stretches 3.0 cm from its relaxed length when a force of 7.5 N is applied. A particle with a mass of 0.5 kg rests on a frictionless horizontal surface and is attached to the free end of the spring: The particle is pulled horizontally so that it stretches the spring 5.0 cm and is then released from rest at t 0. (a) What is the force constant of the spring? (b) What are the period, frequency, f,...
