Question of physics.........

Answer 1

Let the plane firstly was travelling in x-direction and its velocity was = v (in x-direct.)
After travelling half the circle its velocity reamains constant in magnitude bit along (-x direction) = -v (along x-axis)
Therefore, Change in velocity = v - (-v) = 2v= 200Km/hr

Answer 2

Answer:

Option a is the correct answer.

Explanation:

Let the plane firstly was travelling in x-direction and its velocity was = v (in positive x-direcion)

After travelling half the circle its velocity reamains constant in magnitude bit along (in negative x direction) = -v (along x-axis)

Therefore, Change in velocity = v - (-v) = 2v= 200Km/hr
