Question

if initial velocity is 7.time is 4 and displacement is 92 then find acceleration

Answer 1

s=ut+ 1/2 at^2
s=92, u=7 , t=4 ,a=?
92= 7(4) + 1/2 × a × 4^2
92 =28 + 1/2 × a × 16
92= 28 + 8a
92-28=8a
8a=64
a=64/8
a=8m/sec^2 is the acceleration

Answer 2

HEY BUDDY...!!!!

HERE IS UR ANSWER....


___________________

▶️ Given

=> u ( initial velocity ) = 7 m / s

=> t ( time ) = 4 s

=> s ( displacement ) = 92 m

⏺️ First we'll find v ( final velocity )

=> velocity ( v ) = displacement ( s ) / time ( t )

=> velocity ( v ) = 92 / 4

=> velocity ( v ) = 23 m / s

⏺️ Using v = u + at

=> 23 = 7 + a . 4

=> 23 - 7 = 4 . a

=> 16 = 4 . a

=> a = 4 m / s^2


HOPE HELPED..
