If a mass of 12 kg causes a spring to be extended from its equilibrium position by 1.2 mm, how far would the spring elongate if a 175 kg was used?

A spring has a spring constant of 240 N/m and is compressed from its equilibrium position by 75 cm. What is the spring force on the spring?

What is the displacement of spring with a spring constant of 250 N/m if the restoring force is 85 N?

an object moves from the position +16m to the postion +47m in 12s.what is its total displacment

a ball of mass 2.0 kg is released from rest at a height 60 cm above a light vertical spring of force constant k. the ball strikes the top of the spring and it compresses it a distance of 10 cm. neglecting any energy loss during the collision, find the spped of the ball just as it touches the spring? the force constant k of the spring?

what is the result of unbalanced forces

a person walks 25 m east and then walks 31 m at an angle of 36 degrees north of east. what is the magnitude of the total displacement?

a 6 kg cart on a level surface is pulled at a constant velocity of 2 m/s by a constant force of 10 N. What is the friction force opposing the motion?

The body of mass 126g moving with the velocity of 0.875g and ahead of it is the body of mass 9.66kg moving with the same velocity, the big mass collides perfectly elastically with the wall and on its way back collides elastically with small mass.What is the final velocity of the small mass?
