Apen rolls off a 0.55–meter high table with an initial horizontal velocity of 1.20 meters/second. at what horizontal distance from the base of the table will the pen land? a. 0.18 meters b. 0.20 meters c. 0.40 meters d. 0.62 meters

Explanation:

Given that,

Height of the table,

Initial horizontal velocity, u = 1.2 m/s

We need to find the horizontal distance from the base of the table will the pen land. Let t is time taken by the pen to land. Let is the horizontal distance. It is given by :

...........(1)

Using second equation of motion to find time t.

Since,

t = 0.33 s

Use the value of t in equation (1) as :

or

So, the horizontal distance from the base of the table 0.4 meters. Hence, this is the required solution.      

the answer to this is proletariats.
