The ball  that is thrown into the air with a velocity of 44 ft/s, its height in feet t seconds later is given by the following equation:

y=46 ft/s * t - (32.17 ft/s² * t²/2)

The height in (ft) at a time (t) of a body that has been thrown with a certain velocity and is in vertical motion is given by the following equation:

y = vi * t - (g* t²/2)

Where:

  • y = height
  • vi = initial velocity
  • g = gravity
  • t = time

Information about the problem:

  • vi = 46 ft/s
  • g = 32.17 ft/s²
  • y =?
  • t = t

Applying the height formula we get:

y = vi * t - (g* t²/2)

y = 46 ft/s * t - (32.17 ft/s² * t²/2)

<h3>What is the vertical upward launch?</h3>

It is the movement described by an object that has been thrown vertically upwards in which the height and the effect of the force of the earth's gravity on the thrown object are considered.

The block shown above has a mass of 105 g.<br> What is the density of the block? SC.8.P.8.3
zaharov [31]

The density of the block is 1.25 cm³

The correct answer to the question is Option B. 1.25 cm³

To solve this question, we'll begin by calculating the volume of the block. This can be obtained as follow:

Length = 7 cm

Height = 4 cm

Width = 3 cm

<h3>Volume =? </h3>

Volume = Length × Width × Height

Volume = 7 × 3 × 4

<h3>Volume = 84 cm³</h3>

Thus, the volume of the block is 84 cm³

Finally, we shall determine the density of the block. This can be obtained as follow:

Density is defined as mass per unit volume i.e

Density = \frac{mass}{volume} \\\\

Mass of block = 105 g

Volume of block = 84 cm³

<h3>Density of block =? </h3>

Density = \frac{mass}{volume}\\\\Density = \frac{105}{84}\\\\

<h3>Density of block = 1.25 cm³</h3>

Therefore, the density of the block is 1.25 cm³.

Hence, Option B. 1.25 cm³ gives the correct answer to the question.

A hockey puck sliding on a frictionless surface strikes a box at rest. After the collision, the two objects stick together and m
coldgirl [10]

Answer:

Answer:

f) The puck conserves its original momentum but loses some, but not all, of its mechanical energy.

 Explanation:

It is a case of perfectly inelastic collision . So momentum will be conserved because no external force acts on them during the collision . But there will be loss of energy ( kinetic energy ) . It will be in the form of sound or heat that is produced during collision. They will still have some kinetic energy even after the collision.

Lubov Fominskaja [6]

Answer:

600Joules

Explanation:

The energy stored by this battery is calculated using the energy formula;

E = Q× v

Where E is energy

Q is the charge

v is voltage

Hence E = 50 × 12 = 600Joules

Note Q = 12 ampere minute
