Answer:
Image not full.
Explanation:
From what I can see, Displacement is 175m,
Distance will be = 100 + 50 + the hidden value on the bottom right
The given problem can be exemplified in the following diagram:
Since there is no friction or any other external force, the only force acting in the direction of the movement is the component of the weight of the block, therefore, applying Newton's second law:

Replacing the values:

We may cancel out the mass:

Using the gravity constant as 9.8 meters per square second:

Solving the operations:

Therefore, the acceleration is 6.3 meters per square second.
The planet closest to the sun; Mercury.
Explanation:
Gravitational potential energy = mgh = (5)(9.81)(7) = 343.35J.
