Not at all. Density on its own is not sufficient
Given that force is applied at an angle of 30 degree below the horizontal
So let say force applied if F
now its two components are given as


Now the normal force on the block is given as



now the friction force on the cart is given as



now if cart moves with constant speed then net force on cart must be zero
so now we have




so the force must be 199.2 N
Answer:
The strategy we would like you to learn has five major steps: Focus the Problem, Physics Description, Plan a Solution, Execute the Plan, and Evaluate the Solution. Let's take a detailed look at each of these steps and then do an sample problem following the strategy.
Answer:

Explanation:
Given that:
- mass of meteoroid,

- radial distance from the center of the planet,

- mass of the planet,

<u>For gravitational potential energy we have:</u>

substituting the respective values:
