(a) Find the period of oscillation for a spring-mass system where the spring constant (k) is 24 N/m and the mass (m) is 6 kg. (b) Write an equation for x(t) if the spring is stretched to an amplitude of 10 cm from its equilibrium position x = 0 at t = 0. (c) Write an equation for the following initial conditions: at t = 0, the mass is at x = 0 and has a velocity of +3 cm/s.

The velocity of a given object is determined by a = -kv”, k > 0,n > 0 a constant. (This is often used when examining air resistance, but do try to figure out where the method fails.) At t = 0, the object is moving with a positive initial velocity of V, and continues until its velocity reaches zero (if it ever does). (a) Show that the object comes to a rest in a finite amount of time if and...

.A car starts 200 m west of the town square and moves with a constant velocity of 15 m/s toward the cast. Draw a graph that represents the motion of the car a. Where will the car be 10 minutes later? b. When will the car reach the town square? 5. At the same time the car in #4 left, a truck was 400 m east of the town square moving west at a constant velocity of 12 m/s. Add...
