Question

a body starts from rest and start travels with uniform acceleration on a straight line. if its velocity after making a displacement of 32m is 8m/s, its acceleration is?​

Answer 1

Answer:

a = 0.125 m/s²

Explanation:

u = 0 m/s        [initial velocity]

s = 32 m         [displacement]

v = 8 m/s        [final velocity]

Using third equation of motion,

$v^2-u^2=2as\\\\a=\frac{v^2-u^2}{2s}\\\\a= \frac{8 \: m/s - 0 \: m/s}{2 \times32\:m} \\\\a=0.125 \:m/s^2$
