A 4.88-kg bowling ball moving east at 2.41 m/s strikes a stationary 0.95-kg bowling pin.
Immediately after the head-on collision, the pin is moving east at 5.19 m/s. Determine the post-
collision velocity of the bowling ball.

Oxygen and hydrogen gas are at the same temperature t.what is the ratio of kinetic energies of oxygen molecule and hydrogen molecule if oxygen is 16 times heavier than hydrogen.

The softest and hardest minerals are: softest hardest

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
