Pool ball moving is with velocity of 1.5 m/s. It hits a second pool ball of equal mass, initially at rest. After the collision the first ball moves off at 370 angle from its original direction with a speed of 1 m/s. Find the velocity (magnitude and direction) of the second ball after the collision.

What is work? how much work is done to move an object 0 meters?

Describe the function of the endomembrane system? what organelles are involved?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
