Answer
The distance travelled by the body is 131.9m
Explanation
Lᵉᵗ us ᶜᵒnsider consider,
The velocity be u
The acceleration be a
The time taken be t
The distance travelled be s
Formula to be used
s = ut +¹/₂ᵃᵗ²
Given data
velocity,
u = 54km/h
⇒ᵘ = 54×10³/60×60
⇒ᵘ = 13.88 ᵐ/ˢ
Acceleration ,
a = 5m/s²
time taken
t = 5s
Disᵗᵃnce covered
s = ut +¹/₂at²
⇒s = 13.88×5+1/2×5×5²
⇒ s = 69.4 + 62.5
⇒s = 131.9m
Therefore, distance travelled by the body is 131.9m
