Answer:

\boxed {\boxed {\sf E_p= 515.025 \ J}}

Explanation:

Potential energy is found using this formula:

E_p= mgh

The mass of the baby in the carriage is 1.5 kilograms and the height is 35 meters. Assuming this is on Earth, the gravitational acceleration is 9.81 meters per square second.

m=1.5 \ kg \\g= 9.81 \ m/s^2\\h= 35 \ m

Substitute the values into the formula.

E_p= (1.5 \ kg )( 9.81 \ m/s^2)(35 \ m )

Multiply the first numbers together.

E_p= 14.715 \ kg*m/s^2 (35 \ m )

Multiply again.

E_p= 515.025 \ kg*m^2/s^2

  • 1 kilogram square meter per square second is equal to 1 Joule.
  • Our answer of 515.025 kg*m²/s² is equal to 515.025 J

E_p= 515.025 \ J

The potential energy is 515.025 Joules.

P=M(mass)G(Gravity)H(Height)

Gravity=9.8

M=1.5 G=9.8 H=35

so multiply all

=514.5 potential energy

a horse stands on a flat surface if the horse has a mass of 186 kg what is the normal force acting on it
astra-53 [7]
The mass of the horse is 186 kg.

The weight of the horse is
(186 kg)*(9.8 m/s^2) = 1822.8 N

According to Newton's 3rd Law, there is an equal and opposite force between the horse and the surface.
Therefore the normal reactive force is 1822.8 N.

Answer: 1822.8 N

A string is attached to a ball that has a mass of 0.11 kg. A student pulls up on the string so that the ball accelerates upward
enot [183]

Answer:

T=+1.133N

Explanation:

Tension and weight are forces that have opposite directions

Weight is negative (downward)

W=m*g= 0.11kg*(-9.8m/s^2)

W= -1.078N

Tension is possitive (upward)

The total force will be the sum of both (the difference taking in consideration the direction)

Ft= T+W

Also the total force is the product of the mass due to acceleration:

Ft=m*a

Ft= +0.11kg*0.5m/s^2

Ft=+0.055N (upward)

Tension will be the difference between Ft and W:

T= Ft-W

T=+0.055N-(-1.078N)

T=+1.133N

A 0.30-kg object is traveling to the right (in the positive direction) with a speed of 3.0 m/s. After a 0.20 s collision, the ob
andre [41]

Answer:

I = -2.1 kg.m/s

Explanation:

Given,

mass of the object,m = 0.30 Kg

initial speed, v_i = 3 m/s

time of collision = 0.20 s

final speed, v_f = -4 m/s

Impulse = change in momentum

I = m (v_f-v_i)

I = 0.30\times (-4-3)

I = -2.1 kg.m/s

Hence, impulse of the object is equal to I = -2.1 kg.m/s
