Answer:

a) 3.675 m

b) 3.67m

Explanation:

We are given acceleration due to gravity on earth = $9.8ms^-2$

And on planet given = $2.0ms^-2$

A) Since the maximum jump height is given by the formula

$\mathrm{H}=\frac{\left(\mathrm{v} 0^{2} \times \sin 2 \emptyset\right)}{2 \mathrm{g}}$

Where H = max jump height,

v0 = velocity of jump,

Ø = angle of jump and

g = acceleration due to gravity

Considering velocity and angle in both cases

$\frac{\mathrm{H} 1}{\mathrm{H} 2}=\frac{\mathrm{g} 2}{\mathrm{g} 1}$

Where H1 = jump height on given planet,

H2 = jump height on earth = 0.75m (given)

g1 = 2.0 $ms^-2$ and

g2 = 9.8 $ms^-2$

Substituting these values we get H1 = 3.675m which is the required answer

B) Formula to find height of ball thrown is given by

$\mathrm{h}=(\mathrm{v} 0 * \mathrm{t})+\frac{\mathrm{a} *\left(t^{2}\right)}{2}$

which is due to projectile motion of ball

Now h = max height,

v0 = initial velocity = 0,

t = time of motion,

a = acceleration = g = acceleration due to gravity

Considering t = same on both places we can write

$\frac{\mathrm{H} 1}{\mathrm{H} 2}=\frac{\mathrm{g} 1}{\mathrm{g} 2}$

where h1 and h2 are max heights ball reaches on planet and earth respectively and g1 and g2 are respective accelerations

substituting h2 = 18m, g1 = 2.0 $ms^-2$ and g2 = 9.8 $ms^-2$

We get h1 = 3.67m which is the required height

Please help me, im about to cry cause im so confused. Please explain this to me

eduard

$\bold{2.5y=5x-5 }$

$\bold{y=\dfrac{5x-5}{2.5} }$

$\bold{y=\dfrac{2.5(2x-2)}{2.5} }$

$\bold{y=\dfrac{\cancel{2.5}(2x-2)}{\cancel{2.5}} }$

$\bold{ y=2x-2 }$

PLZ HELP ME WITH THIS!!! I WILL GIVE BRAINLIEST!!!

aleksandr82 [10.1K]

Answer:

Yes, because if the answer needed to be negative then the two integers have to be negative since you are adding the both to get a negative response.

Step-by-step explanation:

if it was -5 + (-5) = -10 (negative)

Geometry question pls help

sammy [17]

Answer:

37 degrees

Step-by-step explanation:

As XW and YZ are parallel lines, you can use the co-interior angle rule to solve for x.

This is when you see a C-shape between parallel lines. The rule states that the sum of these two co-interior angles is 180 degrees.

Therefore,

⇒ $3x - 5 + 2x = 180$

⇒ $5x - 5 = 180$ [collect like terms of x]

⇒ $5x = 185$ [add 5 to both sides]

⇒ $x = 37$ [divide both sides by 5]

Hope this helps! :D
