Question

equation of motion for a body starting from rest and moving with constant acceleratiom

Answer 1

Answer:

v = at

s = 1/2at²

v² = 2as

Explanation:

u = 0 m/s

v = u + at

v = at

s = ut + 1/2at²

s = 1/2at²

v² = u² + 2as

v² = 2as

Hope this helps! :)

Answer 2

Answer:-

Given:-

• Initial velocity (u) = 0 m/s
• Acceleration = a (constant)

To Find: Equations of motion according to the given values.

We know, Equations of motion:-

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

where,

• v = Final velocity,
• u = Initial velocity,
• a = Acceleration,
• t = Time taken &
• s = Distance travelled.

• First Equation of motion:-

v = u + at

→ v = 0 + at

→ v = at

• Second One:-

2as = v² - u²

→ 2as = v² - 0²

→ 2as = v²

• Third One:-

s = ut + ½at²

→ s = (0)t + ½at²

→ s = ½at²
