Question

s=25m, u-? t=5 a = 15 Formula S=ut +1/2at 2 ​

Answer 1

Answer:

Here is the answer.

Explanation:

Here,

s=25m

t=5

a=15

u=?

By given formula,

s=ut+1/2at^2

25=u*5+1/2*15*5^2

25=5u+1/2*5*25

25=5u+125/2

25=5u+62.5

5u=25-62.5

5u=-36.5

u=36.5/5

u=-7.5

is it helpful?

and also think that that is a wrong question.

Answer 2

Answer:

u = - 32.5

Explanation:

s = ut+1/2 at^2

25 = u*5+1/2*15*(5)^2

25 = 5u+1/2*15*25

25 = 5u+1/2*375

25 = 5u+375/2

25-375/2 = 5u

50-375/2 = 5u

-325/2 = 5u

u = -65/2

u = -32.5 ANS.
