Question

If a body starts from rest and travels 120m in the 8th second then the acceleration is

Answer 1

Here we will use Second Equation of Motion i.e. s=ut+1/2at^2

120=0*8 + 1/2*a*8^2

120 = 1/2*a*64

120 = 32*a

120/32 =a

3.75 =a

3.75 m/s/s or meter per second per second

Answer 2

Here we will use Second Equation of Motion i.e. s=ut+1/2at^2

120=0*8 + 1/2*a*8^2

120 = 1/2*a*64

120 = 32*a

120/32 =a

3.75 =a

3.75 m/s/s or meter per second per second
