Question

A particle moving on a straight line ultimately comes to rest. What is the angle between its initial velocity and acceleration?

a.180 degrees b.90 degrees c.45 degrees d.zero

Answer 1

Answer:

d), I hope it's helpful please mark me as brainliast

Explanation:

So, a particle moving on a straight line ultimately comes to rest. Then, the angle between its initial velocity and the acceleration is zero because the velocity and acceleration is same direction. Hence, The angle between its initial velocity and acceleration is zero.

Answer 2

The velocity and the acceleration are both vector quantity.

So, a particle moving on a straight line ultimately comes to rest.

Then, the angle between its initial velocity  and the acceleration is zero because the velocity and acceleration is same direction.

Hence, The angle between its initial velocity and acceleration is zero.
