SITUATION 2. A particle moves along the x-axis with an initial velocity vx = 50ft/sec at the origin when t = 0. For the first 4 seconds it has no acceleration, and thereafter it is acted on by a retarding force which gives it a constant acceleration ax = -10. Calculate the velocity and the x-coordinate of the particle for the conditions of t = 8sec and t = 12 sec and find the maximum positive x-coordinate reached by the particle.

5. A 2-kg wrecking ball attached to a spring with a force constant of 30 N/m oscillates on a frictionless, horizontal air track. At t=0, the wrecking ball is released from rest at x=-3 cm (that is, the spring is compressed by 3 cm). Find the maximum speed in m/s.

The board rests on the surface of two drums. At the instant shown, it has an acceleration of 0.44 m/s? to the right, while at the same instant points on the outer rim of each drum have an acceleration with a magnitude of 4.7 m/s². If the board does not slip on the drums, determine its speed in m/s due to the motion. r = 11.3 in a r

The 0.8 kg particle slides across a frictionless horizontal plane. The force P applied to the particle acts on the x- direction but its magnitude varies with time as shown in the P-t diagram. If the velocity of the particle at time t=0 is 3m/s in the direction shown, determine the speed when t=5s. USE IMPULSE-MOMENTUM METHOD.
