Question

${v}^{2} + {u }^{2} + 2gs$
find the value of s when v=25, u=12 and g=10​

Answer 1

Step-by-step explanation:

v^2=u^2+2gs

(25)^2=(12)^2+2(10)(s)

{(625)-(144)}/20=s

s=(481)/20

s=24.05

Answer 2

v² + u² + 2gS = 0

25² + 12² + 2(10)S = 0

625 + 144 + 20S = 0

769 + 20S = 0

769 = (-20S)

769 / -20 = S

S = (-38.45)

As, S is distance traveled so s can't be negative

therfore, S=38.45
