The cannon on a battleship can fire a shell a maximum distance of 36.0 km.
Paraphin [41]

(a)The initial velocity of the shell will be 594.27 m/sec

(b)The maximum height it reaches will be 9000 m.

c)101.249 m meters lower will its surface be 36.0 km from the ship along a horizontal line parallel to the surface of the ship.

d)The error could be significant compared to the size of a target. Option C is correct.

<h3>What is velocity?</h3>

The change of distance with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.

The given data in the problem is

m is the mass of the block = Kg.

u is the initial velocity of fall = m/sec

h is the distance of fall =  m

g is the acceleration of free fall = m/sec²

v is the hitting velocity of =?

a)

The range of the projectile is;

\rm R = \frac{u^2 sin 2 \theta }{g} \\\\ 36 \times 10^ 3 = \frac{U^2 sin 45^0}{9.81} \\\\ U= 594.27  \ m/sec

b)

The maximum height of the projectile is;

\rm H = \frac{u^2 sin 2 \theta }{2g} \\\\ H = \frac{(594.27)^2\times (sin 45)^2}{2 \times 9.81 } \\\\ H = 9000 \ m

c)

The distance between its surface and the ship, measured in a horizontal arc parallel to the surface, will be 36.0 kilometers. The distance from the lower surface is found as;

\rm( R_e + h)^2 = R_e^2+(36)^2 \\\\ (R_e)^2 = h^2+2R_e h= R_e^2 + 12196 \\\\ h^2 + 12800 h - 1296 = 0 \\\\ h = 101.249 \ m

d)

An error is a mistaken or erroneous action. In some contexts, an error is interchangeable with a mistake.

The difference between the calculated value and the original value is known as the error. The inaccuracy may be large in comparison to the target's size. Option C is correct.

Hence the initial velocity of the shell, maximum height, and the distance from the lower surface will be 594.27 m/sec,9000 m, and 101.249 m and option c for question d are correct respectively.

Object A moves with a constant velocity of -10 m/s and object B moves with a constant velocity of 5 m/s. Which object has the la
KonstantinChe [14]
Object A has the larger speed because speed is not a vector quantity, it is scalar. This means that directionality, or in this case the sign of the velocity, doesn’t matter.
Speed = |velocity|
Object a speed =|-10|=10 m/s
Object b speed =|5|=5 m/s

Object a is the answer.

A toy plane with a mass of 20 kg is flying at 10 m/s. What is its kinetic energy?
gladu [14]

Answer:

\boxed {\boxed {\sf A. \ 1000 \ Joules}}

Explanation:

Kinetic energy can be found using the following formula.

E_k=\frac{1}{2}mv^2

where <em>m</em> is the mass and <em>v</em> is the velocity.

The mass of the toy plane is 20 kilograms and the velocity is 10 meters per second.

m= 20 \ kg \\v= 10 \ m/s  \\

Substitute the values into the formula.

E_k=\frac{1}{2}(20 \ kg) (10 \ m/s)^2

Solve the exponent first.

  • (10 m/s)²= 10 m/s *10 m/s= 100 m²/s²

E_k=\frac{1}{2} (20 \ kg) (100 \ m^2/s^2)

Multiply the last two numbers together.

E_k= \frac{1}{2}(2000 \ kg*m^2/s^2)

Multiply by 1/2 or divide by 2.

E_k= 1000 \ kg*m^2/s^2

  • 1 kilogram square meter per square second is equal to 1 Joule.
  • Our answer of 1000 kg*m²/s² is equal to 1000 Joules

E_k= 1000 \ J

The kinetic energy of the toy plane is <u>1000 Joules</u>
