A vector has an x-component

9966 [12]

Explanation:

The magnitude of a vector v can be found using Pythagorean's theorem.

||v|| = √(vₓ² + vᵧ²)

||v|| = √((-309)² + (187)²)

||v|| ≈ 361

You can find the angle of a vector using trigonometry.

tan θ = vᵧ / vₓ

tan θ = 187 / -309

θ ≈ 149° or θ ≈ 329°

vₓ is negative and vᵧ is positive, so θ must be in the second quadrant. Therefore, θ ≈ 149°.

Anika [276]

<u>Answer:</u>

Displacement after 1 second = 4.9 m

Displacement after 2 seconds = 19.6 m

Displacement after 3 seconds = 44.1 m

Velocity after 1 second = 9.8 m/s

Velocity after 2 seconds = 19.6 m/s

Velocity after 3 seconds = 29.4 m/s

<u>Explanation:</u>

We have equation of motion , $s= ut+\frac{1}{2} at^2$ , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

Height of building, displacement = 381 meter

Initial velocity = 0 m/s

Acceleration = Acceleration due to gravity = 9.8 $m/s^2$

Displacement after 1 second = $0*1+\frac{1}{2}*9.8*1^2=4.9m$

Displacement after 2 seconds = $0*2+\frac{1}{2}*9.8*2^2=19.6m$

Displacement after 3 seconds = $0*3+\frac{1}{2}*9.8*3^2=44.1m$

We have equation of motion, v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

Velocity after 1 second = 0 + 9.8 * 1 = 9.8 m/s

Velocity after 2 seconds = 0 + 9.8 * 2 = 19.6 m/s

Velocity after 3 seconds = 0 + 9.8 * 3 = 29.4 m/s
