1) A ball is shot from the ground into the air. At a height of 9.1 m, it's velocity is -->V=(7.6i + 6.1j)m/s.
a) To what maximum height does the ball rise?
b) What total horizontal distance does the ball travel?
2)Imagine that the standard kilogram is placed on Earth's equator, where it moves in a circle of radius 6.40 X 10^6(earths's radius) at a constand speed of 465 m/s due to Earth's rotation.
a)What is the magnitude of the centripetal force on the standard kilogram during the rotation?
