As you ride a bicycle on the sidewalk with a speed of

mixer [17]

Answer:

1.2 seconds

Explanation:

distance = ((final speed + initial speed) * time)/2

Here given:

distance: 3.8 meter

initial speed: 6.4 m/s

final speed: 0 m/s

Solving steps:

3.8 = ((0 + 6.4) * time))/2

3.8 = 3.2(time)

time = 3.8/3.2

time = 1.1875 seconds ≈ 1.2 seconds

A clown at a birthday party has brought along a helium cylinder, with which he intends to fill balloons. When full, each balloon

Furkat [3]

Answer:

11

Explanation:

According to Boyle's law:

$P\times V=constant$

Thus,

$P_{cylinder}\times V_{cylinder}=n\times P_{balloon}\times V_{balloon}$

Where, n is the number of the balloons

From the question, it is given that:

For balloon:

P = $1.2\times 10^5$ Pa

V = 0.040 m³

For cylinder:

P = $1.80\times 10^7$ Pa

V = 0.0031 m³

So,

$1.80\times 10^7\times 0.0031=n\times 1.2\times 10^5\times 0.040$

n = 11.625

So, Maximum number of balloons = 11

A runner moves 2.88 m/s north. She accelerates at 0.350 m/s^2 at a -52.0 angle. At the point in the motion where she is running

MrRissso [65]

The runner has initial velocity vector

$\vec v_0=\left(2.88\dfrac{\rm m}{\rm s}\right)\,\vec\jmath$

and acceleration vector

$\vec a=\left(0.350\dfrac{\rm m}{\mathrm s^2}\right)(\cos(-52.0^\circ)\,\vec\imath+\sin(-52.0^\circ)\,\vec\jmath)$

so that her velocity at time $t$ is

$\vec v=\vec v_0+\vec at$

She runs directly east when the vertical component of $\vec v$ is 0:

$2.88\dfrac{\rm m}{\rm s}+\left(0.350\,\dfrac{\rm m}{\mathrm s^2}\right)\sin(-52.0^\circ)\,t=0\implies t=10.4\,\rm s$

It's not clear what you're supposed to find at this particular time... possibly her position vector? In that case, assuming she starts at the origin, her position at time $t$ would be

$\vec x=\vec v_0t+\dfrac12\vec at^2$

so that after 10.4 s, her position would be

$\vec x=(10.1\,\mathrm m)\,\vec\imath+(17.2\,\mathrm m)\,\vec\jmath$

which is 19.9 m away from her starting position.
