Abook is pushed with an initial horizontal velocity of 5.0 meters per second off the top of a 1.19 meter high desk. how far away does the book land?

A book is pushed with an initial horizontal velocity of 5.0 meters per second off the top of a 1.19 meter high desk. The book lands at 2.45 m.

2.45 m

Explanation:

The book when pushed with the initial velocity of 5 m/s, the book flights down from the high desk which is 1.19 m high. The book takes the projectile motion path and hence to calculate the distance, how far it lands away from the desk can be calculated as follows,

Given that,

v = 5 m/s

h = 1.19 m

As we know that the time can be calculated as the time of flight, by

Putting the values, we get,

Thereby,

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

real, smaller and upside-down.   so the answer should be b.
