An object of mass 24,000 kg, moving horizontally at 0.11 m/s is brought to a halt by a spring, with a spring constant k = 268 kN/m. Assume the spring is initially at the equilibrium position, and find the magnitude of distance which the spring is compressed to bring the object to a halt. Assume energy is conserved. Give your answer in metres, to 2 sf.
Homework Answers
The kinetic energy of the block gets converted to potential energy of spring
KE = PE
0.5mv^2 = 0.5kx^2
24000*0.11^2 = 268000*x^2
x = 0.033 m
So the spring conpresses by 3.3 cm

2. An 10 kg object is hung from a spring attached to a fixed support. The spring constant of the spring is k = 40 N m-1. Suppose an external downward force of magnitude f(t) = 20e-2t N is applied to the object, and damping due to air resistance occurs with damping constant B = 40 N s m-1. Let y(t) denote the distance in metres of the object below its equilibrium position at time t...

A 0.45 kg object rests on a frictionless horizontal surface, where it is attached to a massless spring whose k-value equals 24.0 N/m. Let x be the displacement, where x = o is the equilibrium position and x > 0 when the spring is stretched. The object is pushed, and the spring compressed, until хі =-4.00 cm. It then is released from rest and undergoes simple harmonic motion. (a) What is the object's maximum speed (in m/s) after it is...

An object of mass m = 1.70 kg is travelling on a horizontal surface. The coefficient of kinetic friction between the object and the surface is muk = 0.200. The object has speed v = 1 .35 m/s when it reaches x = 0 and encounters a spring. The object compresses the spring a distance d/2, stops instantaneously, and then travels back to x = 0 where it stops completely. Eventually you will be asked to find the spring constant,...
