Question

s=ut+1/2at^2 u=10, a=-2, t=1/2 work out the value of s

Answer 1

Answer :

Given -

• u = 10 m/s
• a = -2 m/s²
• t = 0.5 s

To Find -

• Value of s ?

Solution -

s = ut + ½at²

Substituting the values,

⇒ s = 10*0.5 + ½*-2*(0.5)²

⇒ s = 5 + (-0.25)

⇒ s = 5 - 0.25

⇒ s = 4.75 m

Hence, Value of s = 4.75 m.

Some Additional Information -

Three equations of motion -

1. v = u + at
2. s = ut + ½at²
3. v² - u² = 2as

Answer 2

Answer:s= 4.75

Step-by-step explanation:

s = ut + ½at²

So,

s = 10*0.5 + ½*-2*(0.5)²

s = 5 + (-0.25)

s = 5 - 0.25

s = 4.75 m

so then, s = 4.75
