Question

An object accelerates from rest to 35m/s over distance of 36 m . What acceleration did it experience

Answer 1

Acceleration : 17.01 m/s²

Further explanation

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration

• An equation of uniformly accelerated motion

vf = vo + at

vf² = vo² + 2a (x-xo)

x = distance on t

vo / vi = initial speed

vt / vf = speed on t / final speed

a = acceleration

`\tt vf^2=vo^2+2ax\rightarrow vo=0\rightarrow rest\\\\35^2=0^2+2.a.36\\\\1225=72.a\\\\x=17.01~m/s^2`
