Gymnasts often
practice on foam floors, which increase the collision time when a gymnast
falls. What effect does this have on collisions
The effect of the gymnast on the collision will increase.
An elastic collision is when two bodies collide and separates after collision
conserving the total kinetic energy before and after collision.
The correct answer is c) 28 m/s.
Let's find the step-by-step solution. The motion of the monkey is an uniformly accelerated motion, with acceleration equal to
. The initial velocity of the monkey is zero, while the distance covered is S=40 m. Therefore, we can use the following relationship to find vf, the final velocity of the monkey:
from which
Answer:
the angular velocity is the same for both.
Explanation:
Angular velocity is defined by the change in angle between time
w = Δθ /Δt
As the arm and elbow are on the same axis the two rotate the same angles, therefore the angular velocity is the same for both.
This does not happen with linear speed
v = w r
therefore as the hand has a greater radius its greater linear speed
Traalate
La velocidad angular es definida por el cambio del angulo entre el tiempo
w= Δθ/ΔDt
como el brazo y el codo están en el mismo eje los dos girar los mismo ángulos, por lo tanto la velocidad angular es la misma para los dos.
Esto no pasa con la velocidad lineal
v = w r
por lo tanto como la mano tiene un radio mayor su velocidad lineales mayor
Answer:
10kg m/s
Explanation:
We can use the conversation of momentum for this question. Essentially the momentum before and after the crash will remain the same. We can use the formula P = mv to solve.
P = 1 * 10
P = 10kg m/s
Best of Luck!
Answer:
A bar magnet creates a magnetic field around it. The field cannot be seen, but its effects can be observed. This is how the magnetic field around a magnet is detected. Iron fillings can be used to study the presence of magnetic field and a compass can be used to plot the field lines.
