A 10-kg mass is attached to a spring, stretching it 0.7 m from its natural length. The mass is started in motion from the equilibrium position with an initial velocity of 1 m/sec in the upward direction. Find the distance at t=0.5 sec, if the force due to air resistance is -90v N. The initial conditions are x(0) = 0 (the mass starts at the equilibrium position) and i(0) = -1 (the initial velocity is in the negative direction). Use 4 decimal palces.

QUESTION 1 A 10-kg mass is attached to a spring, stretching it 0.7 m from its natural length. The mass is started in motion from the equilibrium position with an initial velocity of 1 m/sec in the upward direction. Find the distance at t=0.5 sec, if the force due to air resistance is -90v N. The initial conditions are x(0) = 0 (the mass starts at the equilibrium position) and i(0) = -1 (the initial velocity is in the negative direction). Use 4 decimal palces.
The spring constants are k1 = 200 N / m, k2 = 250N / m and the unstretched lengths of the springs are 0.9 m. The mass of the bracelet is 4 kg. What is the total potential energy at point B with respect to the given datum line when the bracelet left from A reaches point B? Neglect the dimensions of the bracelet. (L1 = 0.90 m, L2 = 1.80 m, h1 = 1.20 m and h2 = 2.40 m)
A spring is stretched 3 cm by a force of 6 N. Thus, according to Hooke's Law, the spring DO = 200 N. Assume as usual, that r = 0 is the equilibrium position. constant is k 0.03 A mass of 8 kg is now attached to the end of the spring, and it is set in motion with initial position xo = 0 and with initial velocity 10 (m) to the left. ( So, v(0) = -10(m).)
A spring is such that a 5 -lb weight stretches it 6 in.

A spring with a spring constant k of 20 pounds per foot is loaded with a 10-pound weight and allowed to reach equilibrium. It is then displaced 1 foot downward and released. If the weight experiences a retarding force in pounds equal to four times the velocity at every point, find the equation of motion. y(t) = where t is time (in seconds) and y(t) is displacement (in feet).
A block of 1:6 kg mass is on a plane inclined to 50 for which the kinetic friction coecient is c = 0:12. The block is connected to a spring of constant k = 5 N=m by a string.
