A 64-kg skater initially at rest throws a 5.0-kg medicine ball horizontally to the left. Suppose the ball is accelerated through a distance of 1.0 m before leaving the skater's hand at a speed of 7.0 m/s . Assume the skater and the ball to be point-like, the surface to be frictionless, and ignore air resistance. Use a vertical y-axis with the positive direction pointing up, and a horizontal x-axis with the positive direction pointing to the right.
A) Determine the acceleration of the ball during the throw.
B) Determine the acceleration of the skater during the throw.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
