starting position
Physics
1 answer:
Sliva [168]4 years ago
3 0

Answer:

The students displacement is 3·√3 blocks, 45° North of West

Explanation:

From the question, we have;

The distance North in which the student walks = 3.0 blocks

The next walking distance West by the student = 3.0 blocks

The displacement of the student = The shortest distance between the student start and final point

By representing the motion of the student in vector format, we have;

\mathbf{d} = 3\cdot \hat{i} + 3\cdot \hat{{j}}

Therefore the magnitude of d is given as follows;

\left | d\right | = \sqrt{3^2 + 3^2} = 3\cdot \sqrt{3} \ blocks

The direction of the student = tan⁻¹(3/3) = 45° West of North

The students displacement = 3·√3 blocks, 45° North of West.

The earth exerts the necessary centripetal force on an orbiting satellite to keep it moving in a circle at constant speed. Which
jenyasd209 [6]

Answer:

E) The centripetal force is always perpendicular to the velocity.

Explanation:

Due to gravity and inertia, the satellite follows a uniform circular motion. In this movement, the velocity is always tangent to the orbit and the centripetal force is directed towards the center. Therefore, there is no net acceleration in the same direction of velocity, which implies that it remains constant.
