Two 5.5 kg balls of clay are thrown at eachother. a red ball of clay is thrown at 9 m/s and a green ball of clay is thrown at 5 m/s. the balls stick together when they collide. what will be the post collision velocity of the balls?

The slope of a velocity time graph over any interval of time gives the during that interval

Which body part transports oxygen removes waste materials in carries nutrients to the body as part of the circulatory system

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
