A child's toy consists of a piece of plastic attached to a spring in the figure below. The spring is compressed against the floor a distance of 2.00 cm, and the toy is released. If the toy has a mass of 90 g and rises to a maximum height of 45.0 cm, estimate the force constant of the spring.  N/m

Use g 9.8 m/s?. %D You have a light spring which obeys Hooke's law. This spring stretches 3.28 cm vertically when a 2.90 kg object is suspended from it. Determine the following. (a) the force constant of the spring (in N/m) N/m (b) the distance (in cm) the spring stretches if you replace the 2.90 kg object with a 1.45 kg object cm (c) the amount of work (in J) an external agent must do to stretch the spring 7.50 cm from its unstretched position

3. Please provide full body diagram with explanation

The force required to slowly stretch a spring varies from 0 N to 243 N as the spring is extended by 15 cm from its unstressed length. What is the force constant of the spring? Please enter a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 1e6, 5.23e-8 Enter answer here 18.225 18.225 N/m Your Answer N/m

11. A 1.30-kg block is pushed against a vertical wall by means of a spring (k = 850 N/m). The coefficient of static friction between the block and the wall is 0.52. What is the minimum compression in the spring to prevent the block from slipping down? cm - ww

A cart with mass m is held at rest against a spring with spring constant k. It is compressed a distance x. When released from rest, it is launched through a frictionless track. It contains a vertical loop 7. with a radius of R. Find the force the track exerts on the cart when the cart goes through the top of the loop in terms of m, k, F, and R and any other constants. R k m

You need to make a spring scale to measure the mass of objects hung from it. You want each 1.0 cm length along the scale to correspond to a mass difference of 0.10 kg. What should be the value of the spring constant?

As shown below, a 3 kg block on a frictionless horizontal surface is attached to a cable and a 526 N/m spring. The block is in equilibrium (Fnet = 0) and the cable has a tension of 16 N. Determine the normal force on the block and how much the spring stretched. FN l=| x

A 31.0 cm long spring is hung vertically from a ceiling and stretches to 36.9 cm when an 8.00 kg mass is hung from its free end. a. Find the spring constant (in N/m). b. Find the length of the spring (in cm) if the 8.00 kg weight is replaced with a 185 N weight.
