Answer 1

Answer:

1,2,6 is correct..............

Answer 2

Given that,

The object is travelling with a constant velocity.

∴ It has a 0 acceleration.

Mathematically,

a = (v - u)/t = a = (v - v)/t = a = 0/t

⟹ a = 0

Or, the option which is correct:-

“Its acceleration is zero.”

For other options:- [Reason why they are not correct]

a. It's acceleration is decreasing: Acceleration is 0. Thus, it isn't decreasing. It is constant.

b. It's acceleration is (- 9.8 m/s²): It is not opposing 'g' (recall what's 'g').

c. It's acceleration is increasing: Acceleration is 0.

d. It's velocity is decreasing: Velocity is constant.

e. It's velocity is increasing: Velocity is constant.

Hope it helped ^_^. 'g' stands for acceleration due to gravity.
