A 30 [kg] baseball player glides forward on ice skates at 2.1 [m/s], and a 0.80 [kg] baseball is thrown at him with a velocity of -27 [m/s]. He finds that after his collision with the baseball, he
slows down. How fast will the baseball player be moving after he catches the ball?
Before he
catches the ball
After he
catches the ball

the answer is 46 mls because when you add the speed per second it increses the speed

answer: its c lololo

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

a.) travels faster in solids because the particles are closer together.
