Question

The velocity of an object change from 10 m/s to 25 m/s in 5 seconds at uniform rate . The acceleration of object is

Answer 1

▶ Solution :

Given :

▪ Initial velocity = 10mps

▪ Final velocity = 25mps

▪ Time interval = 5s

To Find :

▪ Acceleration of object.

Concept :

✒ Acceleration is defined as the ratio of change in velocity to the time interval.

✒ Acceleration can be positive, negative and zero.

✒ It is a vector quantiy.

Mathematically,

☞ a = (v - u)/t

Calculation :

→ a = (25 - 10)/5

→ a = 15/5

→ a = 3m/s^2
