Calculate the potential energy of a 4 kg cat crouched 3 meters off the ground

Physics
1 answer:
NeTakaya3 years ago
5 0

Gravitational potential energy = (mass) x (gravity) x (height)


GPE = (4 kg) x (9.8 m/s²) x (3 m)


GPE = (4 x 9.8 x 3) kg-m²/s²


GPE = 117.6 Joules

The solar mass of the Sun is 1. The orbital period of Jupiter is 11. 9 Earth years. What is the distance between Jupiter and the
cestrela7 [59]

The distance between Jupiter and the sun is 5.2 AU.

According to Kepler's third law, the square of the period of revolution of planets is proportional to the cube of their mean distances from the sun. From this; T^2 = r^3.

Now, we are told that the orbital period (T) is 11. 9 Earth years. We have to make the distance the subject of the formula.

r =T^2/3

r = (11.9)^2/3

r = 5.2 AU

A golf ball is struck at 75 m/s at an angle of 60 degrees. What is the
Gnesinka [82]

Answer:

v_x=37.50

Explanation:

The rectangular components of a vector \vec v having a magnitude v and angle θ are:

v_x=v\cos\theta

v_y=v\sin\theta

The golf ball has an initial speed of 75 m/s at an angle of 60 degrees.

The variables of the equations have the values:

v = 75 m/s

θ = 60°

Substituting into the formula:

v_x=75\cos 60^\circ

v_x=75\cdot 0.5

v_x=37.5~m/s

Without specifying units and with precision to the hundredths place:

\mathbf{v_x=37.50}

An engineer in a locomotive sees a car stuck on the track at a railroad crossing in front of the train. When the engineer first
nordsb [41]

Answer:

a=0.555m/s^2

Explanation:

First we find the distance traveled from the moment the engineer reacts to the car, assuming uniform movement

X=VT

X=(18)(0.45)=8.1m

then we find the distance at which the deceleration begins, which is obtained by subtracting the total distance with the inner result

X=300-8.1=291.9

finally we use the equation for constant acceleration

Vf=0 final speed

Vo=18m/s= initial speed

X=291.9m

(Vf^2-Vo^2)/2X=a

(0-18^2)/(2*291.9)=a

a=0.555m/s^2
