Question

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.

Answer #1

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.)

m
(b) Find the horizontal distance from the edge of the table to the
point where the book strikes the floor.
m
(c) Find the horizontal and vertical components of the book's
velocity just before...

A tennis ball rolls off the edge of a tabletop of height 0.830 m
above the floor and strikes the floor at a point a horizontal
distance 1.50 m from the edge of the table. You can ignore air
resistance.

Jasper the cat slides off the edge of a horizontal tabletop,
0.80 meters above the ground. Hint, his velocity as he leaves the
table is horizontal.
a) If he lands on the floor 1.50 meter from the edge of the
table, what is the magnitude of his initial velocity, vo?
b) What is the magnitude and direction (as an angle with the
floor) of his final velocity as he hits the floor?

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...

A tennis ball rolls off the edge of a tabletop 0.850 m above the
floor and strikes the floor at a point 1.00 m horizontally from the
edge of the table.
Find the time of flight of the ball.
Find the magnitude of the initial velocity of the ball.
Find the magnitude of the velocity of the ball just before it
strikes the floor.
Find the direction of the velocity of the ball just before it
strikes the floor.

A tennis ball rolls off the edge of a tabletop 0.550 m above the
floor and strikes the floor at a point 1.30 m horizontally from the
edge of the table.
Part A: Find the time of flight of the ball. ANSWER: 0.335 s
Part B: Find the magnitude of the initial velocity of the ball.
ANSWER: 3.88 m/s
Part C: Find the magnitude of the velocity of the ball just
before it strikes the floor. ANSWER: 5.08 m/s
Part...

A golf ball rolls off a horizontal cliff with an initial speed
of 11.0 m/s. The ball falls a vertical distance of 13.0 m into a
lake below.
(a) How much time does the ball spend in the air?
s
(b) What is the speed v of the ball just before it strikes
the water?
m/s

A golf ball rolls off a horizontal cliff with an initial speed
of 12.7 m/s. The ball falls a vertical distance of 16.0 m into a
lake below. (a) How much time does the ball spend in the air? (b)
What is the speed v of the ball just before it strikes the
water?

A
12-g bullet moving horizontally with speed of 350 m/s strikes and
remains in a 4.0-kg block initially at rest on the edge of a table.
The block, which is initially 80 cm above the floor, strikes the
floor a horizontal distance from the base of table. What is the
horizontal distance on the floor?

Two balls are rolled off a tabletop that is 0.8 m above the
floor. Ball A has a horizontal velocity of 3 m/s and that of ball B
is 5 m/s.
a. How long does it take each ball to reach the floor after it
rolls off the edge?
b. How far does each ball travel horizontally before hitting the
floor?
