Answer 2

Answer:

Given:

• A body is moving vertically upwards its velocity changes at a constant rate from 50m s-1 to 20 m s-1 in 3second.

Find:

What is Acceleration?

Important Things to Note :-

• Acceleration is the charge of velocity for a unit of time.

• Velocity is vector measurement it's rate of thr direction of a motion.

• -ve signs refers the opposite direct of the acceleration, this -ve signs are known as Retardation.

•Negative sign indicates opposite direction of acceleration as compared to velocity.

•It's also called Retardation or Deceleration.

Using formula:

• Acceleration = Charge of velocity/Time.

Calculations:

• Acceleration = 20 - 50/3

• Acceleration = -30/3 = -10 m/s⁻²

Therefore, -10 m/s⁻² is the acceleration.
