Answer:

East component is: 18.64 m/s

Explanation:

If the resultant is 32.5 m/s directed 35 degrees east of north, then we use the sin(35) projection to find the east component of the velocity:

East component = 32.5 m/s * sin(35) = 18.64 m/s

what is the approximate weight of a 20-kg cannonball on the moon if the acceleration due to gravity is 1.6m/s^2

monitta

On Earth, a cannonball with a mass of 20 kg would weigh 196 Newtons.
With the formula F=mg, where F is the weight in Newtons, m is the mass, and g is the acceleration due to gravity on the Earth which is 9.8m/s^2.
F=20kg x 9.8m/s^2= 196 Newtons

BUT on the moon, acceleration due to gravity is 1.6 m/s^2,
so F=mg=20kgx1.6m/s^2= 32 N

If a man weight 155 lb on earth, specify

Natali [406]

For the answer to the question above, on Earth, a one-pound object has a mass of about 0.453592 kilograms.

Therefore the man's mass is 155 * 0.453592 = 70.30676 kilograms. 

The part about the Moon's gravity is irrelevant. While the weight of a person or object would be different on the Moon, the mass would be the same.

An apple hanging from a limb has potential energy because of its height . If it falls ,what becomes of this energy just before i

sineoko [7]

Answer: Just before its hits the ground it becomes kinetic energy and when it hits the ground it becomes in another form of energy (acoustic energy or thermal energy, for example)

Explanation:

Energy is the ability of matter to produce work in the form of movement, light, heat, among others.

In this sense, according to the Conservation of Energy principle: "energy is not created or destroyed, it is transformed."

So, in the case of the apple, its total energy is conserved.

When the apple is hanging from a limb, it has zero kinetic energy $K_{o}=0$ (because it is at rest) and has gravitational potential energy $U_{o}$ , which depends on the mass $m$ , the acceleration due gravity $g$ and the height $h$ :

$U_{o}=mgh$

When the apple falls, just before its hits the ground, this gravitational potential energy transforms in kinetic energy $K_{1}$ (since the apple is moving), which depends on the mass and velocity $V$ of the apple:

$K_{1}=\frac{1}{2}mV^{2}$

When the apple hits the ground, the gravitational potential energy is zero (h=0) and the kinetic energy transforms into some other form of energy (acoustic energy or thermal energy, for example).

Chameleons catch insects with their tongues, which they can rapidly extend to great lengths. In a typical strike, the chameleon’

Yuki888 [10]

Answer:

0.2 m

Explanation:

PHASE 1

First, we calculate the distance the tongue moved in the first 20 ms (0.02 secs). We use one of Newton's equations of linear motion:

$s = ut + \frac{1}{2}at^2$
