Question

a body travels with a uniform acceleration 15m/s' for an interval of time 5sec and 20m/s2 for an intervals of time 2sec. Find average acceleration​

Answer 1

Answer:

Explanation:

body travels with a uniform acceleration 15m/s' for an interval of time 5sec and 20m/s2 for an intervals of time 2sec. Find average acceleration​

Answer 2

Given :-

A body travels with a uniform acceleration of 15m/s' for an interval of time 5sec and 20m/s2 for an interval of time 2sec.

To Find :-

Average acceleration

Solution :-

We know that

Average acceleration = v - u/t₂ - t₁

Average acceleration = 20 - 15/5 - 2

Average acceleration = 5/3

Average acceleration = 1.66 m/s²

Hence

Average acceleration is 1.66 m/s²
