A 1.5 kg object falls from a height of 2.0 m onto a spring scale with a spring constant of 1.5x10 5 N/m. What is the reading on the scale at its greatest compression?

An orthodontic spring, connected between the upper and lower jaws, is adjusted to provide no force with the mouth open. When the patient closes her mouth, however, the spring compresses by 6.0 mm. What force is exerted if the spring constant is 160 N/m?

A 1.5 kg crate falls from a height of 2.0 m onto an industrial spring scale with a spring constant of 1.5 O 105 N/m. At its greatest compression the reading on the scale is: O a. 3.0 x 103 N O b. 2.1 x 103 N Ос 15 х 103 N O d. 15 N O e. 30 N

A spring (k = 1300 N/m) is used to stop a 1320 kg vehicle initially traveling at 4.1 m/s.    How much is the spring displaced in doing this task?  Δx =    m

You pull the block horizontally, stretching the spring a total of 20 cm from its equilibrium position. The kinetic frictional coefficient between the surface and the block is 0.25. What is the acceleration of the spring right after you let go of it? (b) 0 0 0 0 37.62 42.5 40 m 58.12 www Fspr x = 0 ↑

A 33.0 cm long spring is hung vertically from a ceiling and stretches to 37.5 cm when an 8.00 kg mass is hung from its free end.     (a) Find the spring constant (in N/m). N/m (b) Find the length of the spring (in cm) if the 8.00 kg weight is replaced with a 175 N weight. cm

The cart is attached to a spring which is fixed to the end of the track. The spring has spring constant k = 5 N/m. The cart starts at x=0 cm, where the spring is at the rest length. You pull on the cart, stretching the spring 10 cm beyond the rest length (x = 10 cm), then release the cart from rest. The spring pulls the cart back towards the original equilibrium position. a.) What was the energy of the system just before the cart is released (Point 1 picture)? b.) What is the speed of the cart at x = 8 cm (Point 2 picture)? c.) What is the speed of the cart when it passes through the equilibrium point (x=0)?

A 25.0 cm long spring is hung vertically from a ceiling and stretches to 30.5 cm when a 6.50 kg mass is hung from its free end. HINT (a) Find the spring constant (in N/m). N/m (b) Find the length of the spring (in cm) if the 6.50 kg weight is replaced with a 165 N weight. cm

I need help solving the equations symbolically and I don't know how to get the m value for the first part.

An ideal spring has a constant 2500 N/m. An object is attached to the spring and stretched vertically 4 cm down. What are the magnitude and direction of the force exerted by the spring? 100 N up 62.5 N down 100 N down 62.5 N up
