In lacrosse, a ball is thrown from a net on the end of a stick by rotating the stick and forearm about the elbow. if the angular velocity of the ball about the elbow joint is 30.3 rad/s30.3 rad/s and the ball is 1.35 m1.35 m from the elbow joint, what is the velocity of the ball?

Why is there friction between objects

What are the factors that affect the resistance of a wire?

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.
