Question

Under constant acceleration the average velocity of a particle is half the sum of its initial and final velocities. Is this still true if the acceleration is not constant? Explain.

Answer 1

Answer:

no it's not true if the acceleration is not constant

Explanation:

As when acceleration was constant the time taken was same but when the acceleration is not constant time taken changes

therefore, then in this case ..

we apply the first eqn of motion , ie ,

a = v-u/t
