A spring is attached to the ceiling and pulled 8 cm down from equilibrium and released. The amplitude decreases by 17% each second. The spring oscillates 19 times each second. Find an equation for the distance, D the end of the spring is below equilibrium in terms of seconds, t.

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
