A baby carriage is sitting at the top of a hill that is 21m high. The carriage with the baby weighs 12N. The carriage has... energy. Calculate it = <span>252J</span>
Answer:
Explanation:
m = Masa del coche
g = Aceleración debida a la gravedad = 
h = Altura = 
v = Velocidad del automóvil en la parte inferior de la pista
Aquí asumimos que el automóvil desciende verticalmente. La energía potencial del automóvil se completará convertida en energía cinética en la parte inferior de la pista ya que no hay pérdida de energía.
La velocidad máxima que puede alcanzar el coche es .
Answer: Sound wave can be described by five characteristics Wavelength , amplitude, time period, frequency and velocity or speed
Explanation:
Answer:
Conservation of momentum - causes a recoil of cannon frame after launch
Explanation:
- It is simple, we can apply the conservation of momentum on the system. Initial momentum P_i before shooting is zero. Then after you strike the cannon up, the ball will go to the target however for the momentum to be conserved the cannon frame must move backwards with the same momentum with which the cannon ball is launched.
Hence, the recoil of the cannon frame would be large enough to dislodge you off the ground and throw you a few feet back.
On the starting blocks, sprinters use their feet to push backward. The blocks respond by pressing forward with a force equal to this with their feet.
<h3>What drives the sprinter forward?</h3>
Vertical forces must be larger than the pull of gravity in order to assist the sprinter in moving forward as gravity is pushing him or her downward. The propulsive force is the force that propelled the runner forward.
<h3>Basketball players must jump straight up into the air, but how?</h3>
An interaction diagram and a free-body diagram should be included in your explanation. The player pushes down on the ground, which pushes up against him in return. As a result of his push being stronger than gravity, the player accelerates upward.
