When placing each domino upright, potential energy is conserved in that domino. When kinetic energy is initially added into the first domino, this energy converts the next domino's potential energy to kinetic energy, which is transferred to the next domino afterwards.
Answer:
4.88505 m/s
1.21629 m
Explanation:
= Mass of bullet = 2.5 g
= Mass of block = 215 g
= Velocity of bullet = 425 m/s
= Velocity of block
Here, the linear momentum is conserved
The speed of the combination of mass is 4.88505 m/s
The energy in the system is conserved
The maximum height the combined mass will reach is 1.21629 m
The given is a projectile motion with angle equal to 90° at which the motion would become horizontal. The projectile motion has two components for the distance. The horizontal component would progress at a constant rate each second while the vertical component would become greater as time progress.
In this item, we are asked to determine the amount of time that would be needed for the stone to hit the ground. This can be calculated through the equation,
d = V₀t + (1/2)(gt²)
It is to be noted that V₀ has a y-component equal to zero.
Substituting this value to the equation,
9.8 m = (0) + (1/2)(9.8 m/s²)(t²)
t = sqrt (2) = 1.41 s
Hence, the time would be equal to 1.41 s.
Explanation:
The gravitational potential energy of an object is given by GPE=mgh
where m is the mass of the object, g is the gravitational field strength (9.81 m/s² on earth) and h the height it is lifted at above the GPE reference ground.
Mass 1 has a GPE=m¹gh=(2)(9.81)(10)=196.2 Joule
Mass 2 has a GPE=m²gh=(4)(9.81)(10)=392.4 Joule
Object 2 has more potential energy and it makes sense since it's heavier
Hope this helps :))
