Think of it like this. If you have a cart full of heavy potatoes, it would be hard to push the cart. That is inertia. Because of its weight and gravitational pull, there is inertia.
Answer:
correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.
Explanation:
As we know that string makes an angle with the horizontal
so we can write the force equation for the given ball
also in Y direction
now we have
now we can conclude that train is accelerating with acceleration same as gravity
now correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.

<u>Answer:</u>
15.97 N force is tending to pull Rover forward
<u>Explanation:</u>
The woman pulls on the leash with a force of 20.0 N at an angle of 37° above the horizontal. The arrangement is shown in the given figure,
We nee to find the pulling force P. The 20.0 N force has two components, 20.0 cos 37 in horizontal direction and 20.0 sin 37 in vertical direction.
The horizontal component is equal to pulling force P, which will pull Rover forward/
So, P = 20.0 cos 37 = 15.97 N
15.97 N force is tending to pull Rover forward.
