Proper Length

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

A 2.0-kg object has a velocity of 4.0i ^ m/s at t = 0. A constant resultant force of (2.0i ^ + 4.0j ^ ) N then acts on the object for 3.0 s. What is the magnitude of the object’s velocity at the end of the 3.0-s interval?
A block of mass ?=3.80 kg slides along a horizontal table with velocity ?0=1.50 m/s. At ?=0, it hits a spring with spring constant ?=41.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by ?=0.400. How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.

Three masses m1 = 3.5 kg, m2 = 10.5 kg and m3 = 7 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant of 228.9 N/m. the elevator is moving downward with a velocity of v = -2.7 m/s but accelerating upward with an acceleration of a = 5.4 m/s^2. Find the distance of the upper spring extended from its unstretched length and the force the bottom spring exerts on the bottom mass.
A cannon is rigidly attached to a carriage, which can movealong horizontal rails, but is connected to a post by a large spring, initially unstretched and with force constant k = 2.00 x 104 N/m, as inFigure P6.75.

If the objects are released from rest find the final velocity of cach object.
An object of mass M is hanging from a spring (with l_o =0 and a spring constant k). There is a constant force from the wind, F_wind, blowing to the right, so the mass is initially at rest, but hanging at an angle Theta from the vertical because of the presence of the wind. Suddenly, spring breaks, and the mass drops under the influence of F_air and its weight. If the object (in equilibrium before the spring breaks) is a height H above the ground, how far laterally (in the direction of the wind) does the object hit the ground, L (given theta, k, M, g, H)?
