Answer 2

Answer:

Concept:

Equations of motion are mathematical formulas used to express how a body is moving in relation to a specific frame of reference, including its position, velocity, and acceleration. There are three equations of motion which are

v = u + at

v² = u² + 2as

S = ut + $\frac{1}{2}$at²

where a body has an initial velocity 'u' and a uniform acceleration 'a' for time 't' so that its final velocity becomes 'v'.  The distance travelled by the body in this time be 's'.

Explanation:

Given:

u=5 m/s, a=12m/s², t=3 sec.

To find:

Distance travelled by the body s=?

Solution:

Using this formula

   S= ut + $\frac{1}{2}$at²

By substituting the values,

   S= (5×3) + $\frac{1}{2}$ ×12×(3²)

      =15 + (6×9)

      =15+54

      S=69 m  

Hence the distance travelled by the body(S)=69m
