Question

Derive any 3 equations of motion.

# please answer along with derivation and explanation
#No spams to be tolerated​

Answer 1

Explanation:

Hence, these equations are used to derive the components like displacement(s), velocity (initial and final), time(t) and acceleration(a). Therefore they can only be applied when acceleration is constant and motion is a straight line. The three equations are, v = u + at.

Answer 2

Answer:

Derivation of equations of motion are as follows -

1 - v = u + at

a = v-u/t

at = v-u

v = u + at .

2 - s = Av × t

s = ( u+v ) / 2× t

s = ( u + u + at ) / 2 × t

s = ( 2u + at ) / 2 × t

s = 2ut / 2 + at² / 2

s = ut + ½ at ²

3 - v² = u ² + 2as

s = Av × t

s = ( u + v ) / 2 ( v - u ) / a

2as = v² - u ²

v² = u ² + 2as .
