Question

A body is accelerating along a straight line starting from rest . Displacement of the body in 3 s is 15m. Displacement of the body in 9s is​

Answer 1

Answer: 12.5m

Explanation: Given : a=1 m/s

Given : a=1 m/s 2

Given : a=1 m/s 2 t=5 s

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/s

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 2

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at 2

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at 2

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at 2 Or S=0+

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at 2 Or S=0+ 2

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at 2 Or S=0+ 21

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at 2 Or S=0+ 21

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at 2 Or S=0+ 21 ×1×5

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at 2 Or S=0+ 21 ×1×5 2

Given : a=1 m/s 2 t=5 sInitial speed of the body u=0 m/sDisplacement of the body S=ut+ 21 at 2 Or S=0+ 21 ×1×5 2 =12.5 m
