Heya Yash is here for help you :)
See all steps :)
©©© First equation of motion :)
®® Suppose body is moving with initial velocity 'U' after time interval 't' it's final velocity becomes 'V'. If acceleration produced in body be 'a'
From
=>a=Change in velocity / time
=>a=V-U/t
=>V-U=at
=>V=U+at.......... Proved
>> [Second equation of motion : ]
[If distance covered by body in time 't' be 'S' then]
=>S=Average velocity × time
=>S=(U+V)/2 ×t
=>S=(U+U+at)/2 ×t
=>S=(2U+at/2) ×t
=>S=(2U/t + at/2) ×t
=>S=(U+at/2) ×t
=>S=Ut+1/2 at².......... Proved
******Hope this is helpful for u :)
******Thanks :)
