Picture #1:
GPE = (mass) x (gravity) x (height)
GPE = (2 kg) x (9.8 m/s²) x (40 m) = 784 joules

KE = (1/2) (mass) (speed²)
KE = (1/2) (2 kg) (5 m/s)²
KE = (1 kg) (25 m²/s²)  =  25 joules

Picture #2:
KE = (1/2) (mass) (speed²)
KE = (1/2) (2 kg) (10 m/s)²
KE = (1 kg) (100 m²/s²)  =  100 joules

Picture #3:
GPE = (mass) x (gravity) x (height)
GPE = (20 kg) x (9.8 m/s²) x (2 m) = 392 joules

KE = (1/2) (mass) (speed²)
KE = (1/2) (20 kg) (5 m/s)²
KE = (10 kg) (25 m²/s²)  =  250 joules

Picture #4:
GPE = (mass) x (gravity) x (height)
98 joules = (1 kg) x (9.8 m/s²) x (height)
Height = (98 joules) / (1 kg x 9.8 m/s²)
Height = 10 meters

Picture #5:
GPE = (mass) x (gravity) x (height)
39,200 Joules = (mass) x (9.8 m/s²) x (20 m)
Mass = (39,200 joules) / (9.8 m/s² x 20 m)
Mass = 200 kg

A 7kg bowling ball is at rest at the end of a bowling lane. You push the ball with a force of 22N which induces a -1N of frictio
Valentin [98]

Explanation:

You can find the net force by summing the force components:

∑F = 22 N − 1 N

∑F = 21 N

Or by using Newton's second law:

∑F = ma

∑F = (7 kg) (3 m/s²)

∑F = 21 N

How to find work without force
nikklg [1K]
I’m not sure what variables you are given, but since work = force x distance, and force = mass x acceleration, you could use work = mass x acceleration x distance

a 3-newton force and a 4-newton force are acting concurrently on a point. which force could not produce equilibrium with these t
Paladinen [302]

A force that cannot produce equilibrium with these two forces must be less than 7 N or greater 7 N.

The given parameters;

  • <em>3 Newton force </em>
  • <em>4 Newton force</em>

A body is said to be in equilibrium state when the net force on the body is zero.

A force that produce equilibrium among two forces acting concurrently is known as equilibrant force. This force is usually equal to sum of the two concurrent forces.

F_1 + F_2 = F_3

where;

  • F₁ and F₂ are the concurrent forces
  • F₃ is the equilibrant force

From the given parameters;

F_1 + F_2 = 3 \ N + 4\ N  = 7\ N

Thus, a force that cannot produce equilibrium with these two forces must be less than 7 N or greater 7 N.

Which of the following are properties of a conductor in electrostatic equilibrium? The force on a charge near the conductor is z
ipn [44]

Answer:

The electric field inside the conductor is zero.

Explanation:

In electrostatic equilibrium charges are assumed to be in rest. Therefore no current.

I = 0

From the ohm's law

ΔV= IR = 0

⇒ΔV =0

Therefore, potential V is same through the conductor.

Also, E = -ΔV d = 0

Hence, The electric field inside the conductor is zero.
