Answer:

a) 2.28 m/s²

b) 159.86 m

Explanation:

Part A:

u = 0 m/s

v = 27 m/s

t = 11.8 seconds

a = ?

Formula:

v = u + at

=> 27 = 0 + a(11.8)

=> 27 = a(11.8)

=> a(11.8) = 27

=> a = 27/11.8

=> a = 2.28 m/s²

Part B:

s = ?

Formula:

s = (v² - u²)/2a

s = (27² - 0²) /2(2.28)

  = 729/4.56

  = 159.86 m

Explanation:

Answer:

Power is 3000 W

Explanation:

Momentum = mass × velocity

[tex]300 = 20 \times v \\ velocity = 15 \: {ms}^{ - 1} [/tex]

For power:

[tex]P = \frac{force \times distance}{time} \\ \\ P = force \times ( \frac{distance}{time} )[/tex]

but distance/time is velocity, so:

[tex]P = force \times velocity[/tex]

but force = mass × acceleration:

[tex]P = (mass \times acceleration) \times velocity \\ P = (20 \times 10) \times 15 \\ P = 3000 \: \: watts[/tex]

[ taken acceleration to be 10 m/s² ]

There's a problem with the given information, but I'll get to that later.

Use Newton's second law. When F₂ points east, we have

F₁ + F₂ = (30 kg) (5.0 m/s²) = 150 N

and when F₂ points west, it acts in the opposite direction and

F₁ - F₂ = (30 kg) (10 m/s²) = 300 N

Solve for F₁ and F₂ : we have

(F₁ + F₂) + (F₁ - F₂) = 150 N + 300 N

2F₁ = 450 N

F₁ = 225 N

and

(F₁ + F₂) - (F₁ - F₂) = 150 N - 300 N

2F₂ = -150 N

F₂ = -75 N

But F₁ and F₂ are magnitudes, so they must be positive! Also, it doesn't make sense that when the forces both point east, the mass accelerates less than it does when the forces work against each other. Probably one of the given accelerations are supposed to point west instead of east.

If the scatter plot shows the number of minutes Guya practiced the flute each day in a given week, then Guya practiced 20 minutes on Tuesday, therefore the correct answer is option C.

A set of dots plotted on a horizontal and vertical axis is known as a scatter plot. Because they may demonstrate the degree of connection, if any, between the values of observed quantities or events, scatter plots are crucial in statistics.

As given in the problem If the scatter plot shows the number of minutes Guya practiced the flute each day in a given week,

Explanation:

because all are factors that determine the resistivity of a material

Explanation:

By the formula,

[tex]s=ut+\frac12at^2[/tex]

[tex]-3.5=0+\frac12a(0.809)^2[/tex]

[tex]a=-10.659 ms^{-2}[/tex]

where a is the acceleration of objects by gravity.

We also know that by the Law of Gravitation,

[tex]F=-\frac{GMm}{r^2}=ma[/tex]

[tex]a=-\frac{GM}{r^2}[/tex]

The mass of the planet is given by

[tex]M=\rho V=\rho(\frac 43\pi r^3)[/tex]

So

[tex]a=-\frac{G(\rho\frac 43\pi R^3)}{r^2}= - \frac{(6.67 \times 10^{-11})(5500)(\frac43)\pi R^3}{(R+3.5)^2} = -10.659[/tex]

Since R>>3.5, so we approximate

[tex](R+3.5)^2\approx R^2[/tex]

Solving the last equation,

[tex]R=6936.483 km[/tex]

Answer:

v after 5s = 0.25 m/s, it took 10s to stop, it has traveled 2.5m before stopping

Explanation

We can use the equation of motion with constant acceleration

Given: v0= 0.5 m/s a= -0.05 m/s²

v(5s) = v0 + a×t = 0.25 m/s

Stop => v=0 => v0 + a×t = 0 => t=10s

Distance at t=10s ⇒ x(10) = 0.5×10 + 0.5x(-0.05)x10² = 2.5m
