Question

A body starts from rest with a uniform acceleration. if it travels 100 m in 5s, find the value of acceleration

Answer 1

Answer:

U= 0 m/s ( it started from rest)

S=100 m

T= 5 sec

a=???

using equation of motion

S=ut+1/2at^2

since= U= 0

S=1/2at^2

substituting given information from the question

200=1/2a(5)(5)

400=25 a

400/25=a

a=16

value of acceleration is 16 m/s^2

HOPE IT HELPS!!!!
