Answer:

The velocity of the ball is 3.52 m/s.

Explanation:

A projectile is any object that moves under the influence of gravity and momentum only. Examples are; a thrown ball, a fired bullet, a kicked ball, thrown javelin, etc.

Given that the ball was thrown vertically upward on the top of a skyscraper of height 61.9 m. So that the velocity can be determined by;

u = $\sqrt{\frac{2H}{g} }$

Where: u is the velocity of the object, H is the height and g is the gravitational force on the object. Given that: H = 61.9 m and g = 10 m/ $s^{2}$ , then;

u = $\sqrt{\frac{2*61.9}{10} }$

= $\sqrt{\frac{123.8}{10} }$

u = 3.5185

The velocity of the ball is 3.52 m/s.

A 4 kg block is pulled with 5.6 N of force to the right. The block experiences 1.1 N of friction. What is the acceleration of th

BARSIC [14]

Answer:

The acceleration of the box is 1.125 m/s² towards right.

Explanation:

Mass of the box, $m=4$ kg

Force acting towards right, $F=5.6$ N

Frictional force acting towards left, $f=1.1$ N

Let the acceleration be $a$ m/s².

Now, net force acting on the box towards right is given as:

$F_{net}=F-f=5.6-1.1=4.5\textrm{ N}$

From Newton's second law of motion,

$F_{net}=ma\\4.5=4a\\a=\frac{4.5}{4}=1.125\textrm{ }m/s^2$

Therefore, the acceleration of the box is 1.125 m/s² towards right.

What is the position of the earth, moon, and sun during a new moon?

svetlana [45]

The Moon always rotates about the Earth in its orbit. The position of the Earth, moon and sun during a new moon is Earth is in between Sun and Moon.

When moon has travelled for 14 days, it starts its journey again for the next 14 days. The journey starts from the new moon to the full moon. The position of new and full moon is the same. At this time, the Earth is in between the Sun and the Moon.

Thus, the position of the Earth, moon and sun during a new moon is Earth is in between Sun and Moon.

Pun zapato de golf tiene 10 tacos cada uno con un área de 0.01 pulgadas en contacto con el piso suponga que caminar hay un insta

Mars2501 [29]

Answer:

Las presión ejercida por los tacos sobre el suelo es 900 libras por pulgada cuadrada.

Explanation:

Según la Física, comprendemos que la presión es igual a la fuerza dividida por área. En este caso, el peso de la persona dividida por área total de los tacos de los zapatos de golf suponiendo una distribución uniforme de la fuerza. Es decir:

$\sigma = \frac{W}{n\cdot A_{T}}$ (Eq. 1)
