A student leaves a sidewalk corner walks 3.0 blocks north then walks 3.0 blocks west.what is the students displacement from the

starting position
Physics
1 answer:
Sliva [168]3 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.

a plane travels 204 km, northeast in 15.0 minutes. It also increases elevation by 1.6 km, upward in the same amount of time. Wha
LUCKY_DIMON [66]

Answer:

230 m/s northeast, 1.8 m/s up

Explanation:

204 kilometres = 204000 metres

15.0 minutes = 900 seconds

Velocity = Distance / Time

= 204000 / 900

= 230 m/s northeast (to 2 sf.)

1.6km = 1600 metres

Velocity = 1600 / 900

= 1.8 m/s up (to 2 sf.)
