Question

In a university library, a chemistry student sitting at a chair passes a chemistry book at some angle θ above the horizontal to a biology student sitting at another chair at a horizontal distance of 1.60m from the biology student. The biology student receives the book in 0.569 s. Ignore air resistance.

Find (a) the angle θ from the horizontal

(b) the horizontal and vertical components of the book’s velocity, and the magnitude and direction of its velocity, just before the book reaches the biology student.

(c) the horizontal velocity component of the book’s final velocity with respect to an observer in an elevator moving at 3.0m/s.

Answer #1

I hope it's fine...

A physics book slides off a horizontal tabletop with a speed of
1.10 m/s. It strikes the floor in 0.350 s. Ignore air resistance.
Find
(a) the height of the tabletop above the floor,
(b) the horizontal distance from the edge of the table to the
point where the book strikes the floor, and
(c) the horizontal and vertical components of the book’s
velocity, and the magnitude and direction of its velocity, just
before the book reaches the floor.

A physics book slides off a horizontal table top with a speed of
1.15 m/s. It strikes the floor in 0.500 s. Ignore air resistance.
(Assume the book's horizontal direction and upward are
positive.)
(a) Find the height of the table top above the floor.

(b) Find the horizontal distance from the edge of the table to the
point where the book strikes the floor.

(c) Find the horizontal and vertical components of the book's
velocity just before...
