!!Help!!

Ira Lisetskai [31]

Answer:

s = 37.81 m

Explanation:

Given that,

Mass of an apple, m = 1.5 kg

The apple falls for 2.75s before striking the ground.

We need to find how far the apple dropped before hitting the ground. It means we need to find the distance covered. Using the second equation of motion to find it :

$s=ut+\dfrac{1}{2}gt^2$

u is initial velocity, u = 0 (at rest)

$s=\dfrac{1}{2}gt^2\\\\s=\dfrac{1}{2}\times 10\times (2.75)^2\\\\=37.81\ m$

So, Apple dropped 37.81 m before hitting the ground.

Which exerts more force, the Earth pulling on the moon or the moon pulling on the Earth? Explain.

prohojiy [21]

Answer: the earth

Explanation: Earth exerts a gravitational pull on the moon 80 times stronger than the moon's pull on the Earth. Over a very long time, the moon's rotations created fiction with the Earth's tugging back, until the moon's orbit and rotational locked with Earth.

and that's why the earth pulls the moon

What acceleration will you give to a 27.8 kg

stich3 [128]

Answer:

2.72m/s²

Explanation:

Given parameters;

Mass of box = 27.8kg

Force on box = 75.7N

Unknown:

Acceleration = ?

Solution:

Force is the product of mass and acceleration;

Force = mass x acceleration

Now insert the parameters and solve;

75.7 = 27.8 x a

a = $\frac{75.7}{27.8}$ = 2.72m/s²
