Question

A body starting from rest with a uniform a it travels 100 m in 5 sec calculate its a

Answer 1

Hi there !!

Initial velocity = u = 0

distance traveled = s = 100 m

Time = t = 5 sec

a = acceleration

Equation of motion :-

s = ut + 1/2at²

= 0 + 1/2 a × 5 × 5

100 = 1/2a × 25

1/2a = 100 / 25

1/2a = 4

a = 4 × 2

= 8 m/s²
