Question

if a particle is thrown vertically then it is in air for 20 seconds what is the max height attained by the particle​

Answer 1

Answer:

g=10m/s2

Explanation:

A particle is thrown vertically upwards its velocity at half of the maximum height is 10 Metre per second the maximum height attained by it is

A particle is thrown vertically upwards. Its velocity at half of the height is 10m/s, then the maximum height attained by it will be: (g=10m/s2)

Hope this helps you....

Answer 2

Answer:

Explanation:

ANSWER

Let maximum height be H

From the formula, v  

2

=u  

2

−2gs

(10)  

2

=u  

2

−2gH/2=u  

2

−gH       ........(1)

For attaining maximum height, v=0

0=u  

2

−2gH⇒u  

2

=2gH

Putting the value of u  

2

 in (1),

100=2gH−gH=gH

H=  

g
