A 225 kg motorcycle has 6.8*10 3j of kinetic energy. how fast is it going?

Physics
1 answer:
riadik2000 [5.3K]3 years ago
4 0

Answer:

7.35m/s

Explanation:

Kinetic energy = 1/2 MV^2

From the question

Kinetic energy = 6.8x10^3J

Mass = 225kg

V =?

Using the above formula

We have

6.8x10^3 = 1/2 x 225 x v^2

6.8x10^3 = 112.5 x v^2

Divide both sides by 112.5

We have

6.8x10^3 / 112.5 = v^2

v ^2 = 54.04

V = squared root of 54.04

v = 7.35m/s

A slanted vector has a magnitude of 41 N and is at an angle of 23 degrees north of east. What are the magnitude and direction of
jenyasd209 [6]

Answer:

The horizontal component is 37.74 N to east

The vertical component is 16.02 N to North

Explanation:

Any slant vector has two components

→ Horizontal component = R cos Ф

→ Vertical component = R sin Ф

→ R is the magnitude of the vector

→ Ф is the direction of the vector with positive part of the horizontal axis

A slanted vector has a magnitude of 41 N and is at an angle of 23

degrees north of east

23° north of east means the angle between the vector and the

east direction is 23° (east is the positive horizontal direction)

That means R is 41 N and Ф is 23°

→ R = 41 N , Ф = 23°

→ The horizontal component = 41 × cos(23) = 37.74 N east

→ The vertical component = 41 × sin(23) = 16.02 N North

<em>The horizontal component is 37.74 N to east</em>

<em>The vertical component is 16.02 N to North</em>
