On a frictionless surface, a 3 kg mass is held at x = 20 cm by a
force of 17.2 N. a) What is the spring constant of the spring? b)
What force
would be needed to stretch the spring to x = 35 cm?
Homework Answers
a)
F = -kx
Fapplied = kx
Fapplied = 17.2 = k*(0.20)
spring constant
k = 86 N/m
b)
Fapplied = kx
Fapplied = (86)*(0.35)
Fapplied = 30.1 N
A mass of 9 kg is placed on a horizontal frictionless surface and attached to a...
A mass of 9 kg is placed on a horizontal frictionless surface and attached to a spring. The mass is compressed 0.69 meters on the spring from equilibrium and held still. It is then released and it travels across the horizontal surface, around a frictionless quarter circular ramp, and it is launched into the air vertically and reaches a maximum height of 6 meters above the ground. The same mass is then attached to the same spring and hung vertically...

a 2.0 kg mass moves along a frictionless horizontal surface at a speed of 5.0 m/s. The mass encounters a 30 degree inclined surface with a constant friction force of 1.5 N. At 1 m high (vertical) the surface levels off and is again frictionless. the mass then encounters a spring with k=10 N/m a) how far is the spring compressed after the mass comes to rest? b) how far down the inclined plane will the mass move after bouncing...

A block of mass 0.992 kg rests on a frictionless horizontal surface. The block is attached to an ideal spring. Calibration shows that a force of 0.75 N is required to compress the spring 0.25 cm. A 8.0-g rifle bullet is fired and embeds itself in the block, compressing the spring 15.0 cm before rebounding. (a) What was the speed of the block just after impact? (b) What was the initial bullet speed?
