A uniform rod is 1.5 m long and has a mass of 10 kg. It is pinned at point A, a frictionless pivot. The rod is released from a rest position 45o from the horizontal. The top of an undeflected ideal spring is located at point B to contact the tip of the rod when the rod is horizontal. The spring has a constant of 98 kN/m. What is the velocity of the rod’s tip when the rod becomes horizontal?

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
